 Title      
 Abstract    The crystal structure determination of the new rhodium(III)-complex [(DM L)(C5Me5)ClRh](PF6). DML = 1,3-dimethyllumazine, reveals 0 4,N5 coordination of the metal to DML with not very different bond lengths of 213.0(2) pm (R h -N) and 219.2(2) pm (R h -O). This result stands in contrast to the previously reported structure of a cationic dihydrobiopterin bound to [Mo(0)C13] which exhibited a very unsymmetrical chelate ar­ rangement. Chemical and electrochemical two-electron reduction of the Rh(III) complex led to a very labile Rh(I) species (DM L)(C5Me5)Rh which is distinguished by an intense charge transfer band in the visible. The results confirm the characterization of DML as a weak o donor In acceptor ligand with a rather low-lying tc* orbital.

 Abstract    Single crystals of the new com pounds CuLn2[B20 5]2 (Ln = Er3+(I), Lu3+(II)) were ob­ tained by a B9O 3 flux-technique. They crystallize in the space group C ih -P 2 \lc with I: a = 453.14(6); b = 721.94(5); c = 929.5(4) pm; ß = 90.01(3)°; Z = 2 und II: a = 451.4(4); b = 718.3(1); c = 928.1(3) pm; ß = 90.00(6)°; Z = 2. The compounds are isotypic to CuTm2[B20 5 ] 2 as well as to the mineral Gadolinite (FeY 2 [B eSi0 5 ]2) and exhibit layer like 2.[B20 5]4 --anions consisting of edge sharing B 0 4 -tetrahedra, which form four-and eight-membered rings. The borate anions are separated by layers of elongated C u 0 6-octahedra and slightly distorted tetragonal L n 0 8-antiprisms.

 Title    Kristallstrukturuntersuchung an einem bismuthaltigen Hollandit: Crystal Structure Investigation of the Bismuth Containing Hollandite: Bij 9Cu4V40 16  
 Abstract    Single crystals of B^ 9Cu4V 4O i6 have been prepared by quenching of CO2-LA SER heated samples. They were investigated by X-ray techniques. The compound^ crystallizes with tetra­ gonal symmetry, space group C4h-I 4 /w , a = 9.945(2) A, c = 2.915(3) A, Z = 1, and is isotypic to the mineral Hollandite. B^ 9Cu4V4O i6 is the first Hollandite with a statistical distribution of vanadium and copper in the network o f octahedra. Calculations of the Coulomb terms of lattice energy led to a distance o f bismuth to the lone pair of 1.07 A. Considering the lone pair as part of the coordination sphere of Bi3+ a square pyramidal polyhedron is obtained.

 Abstract    The compounds EtPh3PI3, EtPh3PI5 and EtPh3PI7 have been prepared by the stoichiometric reaction of EtPh3PI with iodine in a mixture of dichloromethane and ethanol. EtPh3PI3 cry­ stallizes in the monoclinic space group P2,/n with a = 1176.7(3) pm, b = 1202.5(3) pm, c = 1565.9(4) pm, ß = 93.22(2)° and Z = 4. The crystal structure has been refined to R f =0.043 for 3394 reflections. EtPh3PI5 crystallizes in the monoclinic space group I2/a with a = 1913.9(4) pm, b = 1239.0(2)pm, c = 2435.1(4) pm, ß = 115.84(1)° and Z -8 . The crystal structure has been refined to R f = 0.052 for 3043 reflections. EtPh3PI7 crystallizes in the orthorhombic space group Pbca with a = 1702.7(4)pm, b = 1952.5(4) pm, c = 1809.8(4) pm und Z = 8 . The crystal structure has been refined to R f = 0.053 for 3208 reflections. The structures may be described as layerlike packings of cations Ph3EtP+ and of anions If , I f and I f , respectively. The isolated triiodide ion If is slightly asymmetrical and slightly bent as expected. The pentaiodide ion If forms iodine ribbons like a rope ladder. The heptaiodide ion I f is composed of pentaiodide groups and iodine molecules connected to puckered anionic layers.

 Abstract    Single crystals of the so far unknown compounds KCuGd2M o4O t6 (I) and KCuTb2M o40 16 (II) have been prepared by flux technique. The compounds crystallize with monoclinic sym­ metry. space group C^h-C 2 /c with (I): a = 5.278(2), b = 12.666(5), c = 19.604(14) Ä; ß = 92.76(6)°; (II): a = 5.259(13), b = 12.616(3), c = 19.556(9) A, ß = 92.93(4)°, Z = 4. M olyb­ denum exhibits tetrahedral coordination. The surroundings of copper can be described by distorted tetrahedra, capped by two more distant oxygen atoms, and the rare earth ions show a square antiprism. Potassium is inside an irregular polyhedron. The relationship of the structures o f (I) and (II) is discussed with respect to the KLnMo2Os type compounds. Coulomb term calculations of the lattice energy indicate an oxidation state of copper higher than Cu1.

 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.

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.

 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.
