 Title    Ba2Na(CN2)(CN)3, ein neues Cyanamid-cyanid mit interpenetrierenden Teilstrukturen Ba2Na(CN2)(CN)3, a Novel Cyanamide Cyanide with Interpenetrating Substructures  
 Abstract    Ba2Na(CN2)(CN)3 was obtained by the reaction of Ba2N with melamine and NaCN at 700 °C. The compound was structurally characterized by single-crystal X-ray investigations (Fd3m, a = 1518.8(3) pm, Z = 16). In the crystal structure the Ba"+ ions form a cubic close packed arrangement, the Na+ and the CN2_ ions occupy the octahedral interstices. The CN-ions are located within the close packed Ba2+ layers. The unit cell of Ba2Na(CN2)(CN)3 contains two interpenetrating substructures of the zinc-blende structure type, building up a variant of NaTl. A reversible phase transition has been observed during cooling of the compound. Whereas the Ba2(CN2)(CN)3 sublattice remains nearly unaffected in this process, the Na+ ions of the low-temperature phase are statistically distributed on two crystallographic positions.

 Title    Die Kristallstrukturen von 1,4-Dimethylpiperazinium-tetrabromo- cobaltat(II) und -zinkat(II), (dmpipzH2) [Mn Br4] (M = Co, Zn)  
 Abstract    The Crystal Structures of 1,4-Dimethylpiperazinium Tetrabromocobaltate(II) and -Zincate(II), (dmpipzH2) [MHBr4] (M = Co, Zn) The compounds (dmpipzH2)[MnBr4] (M = Co, Zn) crystallize at room temperature from equi-molar solutions of 1,4-dimethylpiperazine and MBr2 • n H20 in 3M HBr. (dmpipzH2)[CoBr4] is isotypic with the homologous chlorometalates of Co and Zn and crystallizes in the mono­ clinic space group P2,/m with a = 6.424(3), b = 14.588(6), c = 7.102(6) A, ß = 90.87(6)°, Z = 2. (dmpipzH2)[ZnBr4], however, crystallizes in the monoclinic space group P2,/c with a = 7,605(5), b = 13,760(9), c = 13,286(7) Ä, ß = 93,03(6)°, Z = 4. Both structures con­ tain centrosymmetric cations (dmpipzH2)2+ in the chair form and slightly distorted tetrahedra [MBr4]2~ with a mirror plane in the case ofM = Co. Several distances N- • -Brin both structures are interpreted in terms of N-H- • Br hydrogen bonds which are favoured by the packing in the case of M = Zn.

 Title    Synthese und Struktur von Zn(HS0 4)2(H2S0 4)2 und Cd(H S04)2 Synthesis and Structure of Z n(H S04)2(H2S 0 4)2 and C d(H S 04)2  
 Abstract    From the binary systems M2S 0 4/H2S 0 4 (M = Zn, Cd), two new hydrogen sulfates, (Zn(HS0 4)2(H2S04)2 and Cd(HS04)2, have been synthesized and structurally characteri­ zed. Both compounds crystallize in the monoclinic space group P2,/c with cell parameters a = 5.047(2), b = 15.430(4), c = 7.958(3) A and ß = 104.16(4)° (Z= 2) for Zn(HS04)2(H2S 0 4)2 and a = 5.339(1), b = 13.351(3), c = 8.508(2) A and ß = 92.22(3)° (Z = 4) for Cd(H S04)2. In the zinc compound there are slightly distorted centrosymmetric Z n 06 octahedra with Z n -0 distances of 2.05 -2.13 A which are sharing corners with S 0 4 tetrahedra. H S 04 and H2S 0 4 tetrahedra are linked via hydrogen bonds to form layers perpendicular to the c-axis. In the crystal structure of C d(HS04)2there exist two crystallographically different H S 04 tetrahedra. The C d06 octahedra with C d -0 distances between 2.24 and 2.31 A are strongly angle-distorted. Besides hydrogen bonds of medium strength (d0...o = 2.66 A) there are also much more weaker ones (d0...0 = 3.04 A). Considering these latter ones zigzag chains in z-direction can be recognized. The relatively low stability of Cd(H S04)2 in comparison with other metal-II-hydrogen sulfates is discussed with respect to its structural pecularities.

 Title    Synthese und Struktur saurer Ubergangsmetallsulfate - Ti(H50 2)(S 0 4)2(H20 ) 2 und Zr(H30 ) 2(S 0 4)3 Synthesis and Structure of Acid Transition Metal Sulfates - Ti(H50 2)(S 0 4)2(H20 )2 and Zr(H30 ) 2(S 0 4)3  
 Abstract    From the ternary system Mn(S 0 4)n/2 / S 0 3 / H20 (Mn+ = Zr4+, Ti3+) two new acid metal sulfates, Ti(H50 2)(S 0 4)2(H20)2 and Zr(H30) 2(S 0 4)3, have been synthesized and structurally characterized. Ti(H50 2)(S 0 4)2(H->0)i crystallizes in the orthorhombic space group Pnma with cell parameters a = 9.858(5), b = 18.32(2), c = 5.437(7)Ä (Z = 4); Zr(H30) 2(S 0 4)3 crystallizes in the triclinic space group PI with cell parameters a = 5.092(2), b = 8.533(3), c = 12.388(6)A, a = 92.95(3)°, ß = 90.89(3)°, 7 = 94.35(3)° (Z= 2). In the titanium compound there are slightly distorted T i0 6 octahedra with T i-0 distances between 1.99 and 2.09 A which are sharing corners with S 0 4 tetrahedra. Through hydrogen bonds layers are formed perpendicular to the 6-axis. These layers are connected by H30 + ions only. The structure of Zr(H30) 2(S 0 4)3 consists of three different S 0 4 tetrahedra and distorted Zr07 polyhedra which are connected via common corners and edges to form columns parallel to the a-axis. The Z r-0 distances vary from 2.13o to 2.18A for equatorial positions, significantly longer than the axial Zr-O distances with 2.05A.

 Abstract    Tetraselenidoarsenates(V) and -antimonates(V), Rubidium, Cesium, Methanolothermal Synthesis, Crystal Structure Methanolothermal reaction of M2C 0 3 (M = Rb, Cs) with E2Se3 (E = As, Sb) and Se at temperatures in the range 180 -200°C leads to the formation of tetraselenidoarsenates(V) and -antimonates(V) M3ESe4 in moderate to quantitative yields. All four compounds crystallize in the (NH4)3AsS4 structure type (space group Pnma) and contain isolated slightly distorted tetrahedral ESe4~ anions with crystallographic Cs symmetry. Both of the independent cations are coordinated in an irregular manner by seven Se atoms.

 Title    Preparation and Crystal Structure of the Mercury(I) DimoIybdate(VI) Hg2Mo20 7  
 Abstract    Crystal Structure, Magnetic Susceptibility, Mercury Molybdates(VI) Yellow, flat, needle-shaped, diamagnetic crystals of Hg2Mo20 7 were obtained by decompo­ sition of Hg2M o 0 4 in evacuated, sealed silica tubes at 550 °C. Their crystal structure was determined from four-circle diffractometer data: P I, a = 709.7(2), b -714.4(2), c = 803.8(2) pm, a = 64.89(1)°, ß -66.09(1)°, y = 66.45(1)°, Z = 2, R = 0.030 for 3165 structure factors and 66 variables. The molybdenum atoms are coordinated by four oxygen atoms at 171 to 195 pm in a very distorted tetrahedral arrangement. These tetrahedra are linked via a com­ mon oxygen atom, thus forming Mo20 7 groups. The tetrahedral oxygen coordination of each molybdenum atom is augmented by two additional oxygen atoms at 218 to 231 pm, which leads to a distorted octahedral coordination for the molybdenum atoms. These M o 0 6 octa-hedra are connected via common corners and edges and in this way they form two-dimen-sionally infinite sheets, which are separated by the

 Title    Polysulfonylamine, LXX [1] Das Assoziat EtOH *** OH2 als Bindeglied in einem quaternären 18-Krone-6-Neutralmolekül-Komplex: Bildung und Kristallstruktur von (CH2CH20 ) 6-2 H20 -2 EtOH -2 H N (S 02Ph)2  
 Abstract    Di(benzenesulfonyl)amine, 18-Crown-6, Quaternary Complex of Uncharged Molecules, Crystal Structure Co-crystallization of 18-crown-6 (18 C 6) and di(benzenesulfonyl)amine from dry ethanol at -2 0 °C affords the thermally labile and structurally uncharacterized ternary complex 18C 6-2 EtOH-2 H N (S 0 2Ph)2 (2). Single crystals of the quaternary complex 18C6-2 H20 -2 E tO H -2 H N (S 0 2Ph)2 (1) were fortuitously obtained by repeated recrystallization of a sam­ ple of 2 from ethanol that was not kept completely dry. The crystal packing of 1 (triclinic, space group P I) is built up from isolated formula units displaying crystallographic inversion symmetry and pseudo D3d symmetry of the crown ring. The water molecules are located on opposite sides of the ring plane. Each H20 is connected to two Oc atoms of the crown separated by a [CH2CH2OCH2CH2] segment (OwH --O c 210 and 208 pm, angles at H 169 and 164°), and accepts an O -H —Ow hydrogen bond from an ethanol molecule (H —Ow 176 pm, angle 177°). The H N (S 0 2Ph)2 entities in turn are N-H-O bonded to the ethanol molecules (H —O 177 pm, angle 177°).

 Title    Verteilung und Valenz der Kationen im Spinellsystem ZnFeGa04-F e 2G a 0 4 Distribution and Valence of the Cations in the Spinel System Z n F eG a 0 4-F e 2G a 0 4  
 Abstract    For the spinel system Zn1_A ;F e^ G a/l(Fe1+/lG a1_ /l)04 the index X has been determined by X-ray measurements: X = 0 in the region 0 < x < 0,35; the increase of X to 0,62 within 0,35 < x < 1 is nearly linear. The distribution of Fe2+ and Fe3+ ions over the lattice sites has been derived from lattice constants and ionic distances, and also by Mössbauer spectroscopy. In the spinels with x < 0,3 the tetrahedral sites are preferably occupied by Fe2+ ions, for x > 0,5 Fe3+ ions dominate. At x = 0,4 the occupation of the lattice sites by iron ions is statistical, the high temperature Mössbauer spectrum shows a single line only. All spinels are n-type hopping conductors mainly conducting via the octahedral sites.

 Title    R obert  
 Abstract    The ternary compound Ce8Pd24Sb is very close in composition to the intermediate valent binary CePd3. A single crystal study yielded a cubic cell with a = 8.461 (1)A, Pm3m symmetry with wR2 = 0.0412 based on 1453 reflections (222 unique) and 16 parameters. This new structure type is composed of distorted perovskite and Cu3Au subcells arranged with the perovskite-like units centred on the corners of the cube. Fitting the magnetic susceptibility data above 100K to a Curie-Weiss expression yielded a Weiss constant of -15(3)K (anti­ ferromagnetic) and an effective high temperature moment per cerium of 2.45(4)/<B indicating trivalent cerium. No ordering was observed above 3K.

The structures of compounds 1, 2a, 2b, 3a, 4 and 5 have been determined by single crystal X-ray diffraction. The [V20 2F4(C40 4)2]4' ion in 1 consists of the planar V20 2F4 core with the vanadium sites bridged by two ,«-l,2-squarato ligands. The un­ ique cone-shaped [V303F4(C40 4)3]4" ion in 2a and 2b contains a central defect and severely distorted V 3F4 cubane unit. Each vanadium atom bears a terminal oxo ligand; pairs of vana­ dium atoms are bridged by ^-1,2-squarato ligands. The [Mo4O 10F6(C4O4)]4" ion in 3a consists of a squarate ion, which is coordinated to four metal centers. Pairs of metal atoms are bridged by 1 M(0)i «(F)-bridges. Two terminal oxo ligands and one terminal fluoro ligand complete the metal coordination. Oxo and fluoro ligands are partly disordered. The structure of the [Mo30 8F(C40 4)2]3' ion in 4 is related to the structure of [V303F4(C40 4)3]4\ It consists of a defect Mo3(0 3F) cubane unit. Two pairs of molybdenum atoms are bridged by ^-1,2-squarato ligands. Terminal oxo and dioxo groups complete the molybdenum coordination. The [Mo20 3Cl3(C40 4)2]3" ion in 5 exhibits a unique structure with a planar OClMo(w-0)(u-Cl)MoOCl core and a cis, ds-orientation of the oxygen ligands. Two ,«-1,2-squarato ligands bridge the molybdenum centers above and below the Mo20 3Cl3 plane.

 Title    The Oxidation of Partially Acylated Myoinositols  
 Abstract    1,3,4,6-Tetrakis-and 1,3,4,5,6-pentakis-acylmyoinositols are obtained by the controlled cat­ alyzed acylation of myoinositol. The extent of the substitution depends both on the reaction conditions and the structure o f the acylating agent, including steric factors. Chromic acid oxidation converts the acylmyoinositols into the corresponding 2-ketones. Under electron impact, the compounds undergo stepwise deacylation.

The crystal structure is characterized by i [ B a M 0 12]-chains along [010]. In the first case the M positions are occupied by copper by about 41%, in the second case these positions remain com pletely unoccupied. With respect to the crystal chemistry of the reference compound Ba(Cu0.22Mg() 78)Nd2Mo4O 16 all substan­ ces of the composition BaLn2M o40 16 should be written as Ba»Ln2Mo40 16 indicating the holes in th e^ B a M O i^ -c h a in s by ■.

 Title    Ein Oxometallat mit eindimensional flächenverknüpften Oktaederketten Synthesis and Crystal Structure of (C u,Fe)363M o3O i2. An Oxom etallate Showing One-Dimensional Chains of Face Sharing Octahedra  
 Abstract    Single crystals of (C u ,F e)3-63M o30 12 have been prepared by crystallisation from melts. X-ray investigations lead to orthorhombic symmetry, space group D : 2-P 2 12121, a = 5.0952(8), b = 10.637(2), c = 17.881(3) A , Z = 4. (C u ,F e)363M o3O i2 is isotypic to Cu385M o30 12 or (C u,Z n)3 75M o30 12. M olybdenum shows tetrahedral coordination by oxygen. Cu+ and Fe2+ are probably distributed statistically over four different point positions. Interesting features of the crystal structure are one-dim ensional chains of face shared (C u ,F e)0 6 octahedra.

 Title    Binding of Cations to 4 f Metal Ions : Preparation and Properties of Lanthanide(III) Complexes Containing the Phenelzinium(l+) Cation as a Ligand  
 Abstract    Treatment o f Ln2(S 0 4)3 • nH 20 (Ln = La, Ce, Pr, Nd, Sm. Eu, Gd ; n -8, 9) with phenelzine dihydrogen sulfate, (phzH2) S 0 4, in 1 N H2S 0 4 yields polymeric complexes with the general formula [L n (S 0 4)2(H 20) 2(phzH)], which contain the phzH+ cation as a ligand. The compounds have been characterized by elem ental analyses, X-ray powder patterns, thermal methods, magnetic susceptibilities and spectroscopic (IR, Raman, electronic diffuse reflec­ tance and solid-state emission f -f spectra) studies. The prepared complexes most probably consist of 7-coordinated units, formed by four bridging bidentate sulfato groups, two terminal aqua m olecules and one cationic phzH+ ligand.
