 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    Synthese, Kristallstruktur und Eigenschaften von Tetraaminophosphoniumchlorid [P(NH2)4]C1 Synthesis, Crystal Structure, and Properties of Tetraaminophosphonium Chloride [P(NH2)4]C1  
 Abstract    [P(NH2)4]C1 has been prepared by ammonolysis of phosphorus pentachloride in liquid ammonia. The product was purified by reacting the byproduct, ammonium chloride, with diethylamine and removing the diethylamine hydrochloride. Suitable single crystals were obtained from an acetonitrile solution in a temperature gradient between 60 °C and room temperature. The crystal structure of [P(NH2)4]C1 has been determined by single crystal X-ray methods (Pbcn, a = 470.8(2), b = 1622.3(3), c = 756.3(2) pm, Z = 4). In the solid, [PfNH2)4]+ and Cl~ ions are found, resembling a Til-analogous structure. The N -H -C l distances indicate N -H — Cl hydrogen bonding interactions. The distortion of the P-N sceleton of the cation and the very short P -N H 2 distances (mean value: 161.2 pm) have been confirmed by ab initio calculations, which show a generalized anomeric effect of the electron pairs at nitrogen and pjrdjr bonding.

 Title    Uber ein Barium-Lanthanoid-Oxozinkat-Platinat(IV): Ba17Ybi6Zn8Pt40 57 On a Barium Rare Earth Oxozincate-Platinate(IV): B a j 7 Yb 16Z n8Pt40 57  
 Abstract    Reactions of B a C 0 3, ZnO and Yb20 3 mixtures at temperatures up to 1300 °C using plati­ num crucibles led to yellow needles of B a17Y b 16Zn8Pt40 57. The compound crystallizes with a hitherto unknown tetragonal crystal structure, space group C-4h-I4/m, a = 22.731(1), c = 5.682(1) A , Z = 2. The crystal structure is characterized by P t 0 6 octahedra and tetragonal Z n 0 5 pyramids. Yb3+ shows a mono-capped trigonal prismatic coordination and Ba2+ several different coordination environments (C .N = 9 to 10, by O2"). The relationship to the Ba5Ln8M40 2i type is discussed.

 Abstract    Single crystals of NaSr3I r 0 6 have been prepared by heating mixtures of Na20 2, SrO and iridium in closed silver tubes and were investigated by X-ray techniques^ NaSr3I r 0 6 crystal­ lizes with trigonal (rhombohedral) symmetry in the space group D 3d-R 3 c , a = 9.636(2), c = 11.556(3) A , Z = 6, and is isotypic to compounds of the Sr4P t 0 6 type. The substitution of Sr2+ by N a+ in NaSr3I r 0 6 led to an ordered metal distribution and an increase of the oxida­ tion state from IrIV to Irv.

 Title    Preparation and Crystal Structure of the Isotypic Carbides Ln3.67TC6 (Ln = rare earth elements; T = Mn, Fe, Ru) and Eu3 ,i6NiC6  
 Abstract    The 14 carbides Ln367MnC6 (Ln = La-Nd) and Ln367TC6 (Ln = La-Nd, Sm; T = Fe, Ru) were prepared from the elem ental components by arc-melting and subsequent annealing. Eu3 16N iC 6 was obtained from a lithium flux. The crystal structures of these nearly isotypic, hexagonal compounds (P63/m, Z = 2) were determined from single-crystal X-ray data; La3 67. FeC6: a = 878.7(2), c = 535.1(1) pm, R = 0.052 for 548 structure factors and 25 variable parameters; Eu316NiC6: a -860.0(1), c = 548.2(2) pm, R = 0.015 for 606 structure factors and 25 variables. The structures differ from the previously reported Gd3Mn2C6 structure by the occupancy of one manganese position by rare earth atoms. Since the lanthanum atoms are larger than the manganese atoms, only two thirds o f these manganese positions can be occupied by the lanthanum atoms in La3 67FeC6. Eu316NiC6 has similar atomic positions. The C-C bond distances in the C2 pairs are 130(2) and 126.5(5) pm in the La and Eu compounds, respectively. Magnetic susceptibility measurements with a SQ U ID m agnetom eter indicate La3 67FeC6 to be Pauli paramagnetic. A test for superconductivity was negative down to 3 K.

X-ray investigation led to the space group (I): S4 -P4 (Nr. 81) with a = 715.4(1), c = 976.2(3) pm, Z = 1 and (II): C | -P3, (Nr. 144) with a = 712.2(1), c = 693.5(2) pm, Z = 3. While (II) is isotypic to the Stillwellite structure, Pb^(As04)[B(As04)4] represents a completely novel type of crystal structure. Boron and arsenic are tetrahedrally coordinated by oxygen. These polyhedra form two kinds of isolated anions: A s04'~ and B(A s04)49_. Lead is eightfold coordinated by oxygen.

 Title    Ba2KZn3(B306)(B60 13)  
 Abstract    Single crystals of the new compound Ba2KZn3(B30 6)(B60 | 3) were obtained by using a B20 3 flux technique; they crystallize in an as yet unknown structure type. X-ray investigations led to the space group C '-P l (Nr.2) with lattice parameters a = 705.2(2), b = 712.5(2), c = 1880.3(6), a = 93.43(3)°, ß = 90.72(2)°, 7 = 119.57(2)°, Z = 2. The structure contains (B30 6)3~-rings and a new discrete (B60 13)8~ anion, which is composed of two B 0 4 and two B20 5 units. Zn-+ is tetrahedrally coordinated by oxygen and two out of three tenfold coordinated Ba-sites are statistically occupied by Ba2+ and K+.

 Title    Eine neue Verbindung im System Ba/Ln/Zn/Pt/O: Bs^Sn^Zi^PtOis On a New Com pound in the System B a/Ln/Zn/Pt/O : Ba4Sm 4Z n3P tO |5  
 Abstract    Reactions of mixtures of B aC 03, ZnO, Sm20 3 (3:5: 1) heated in platinum crucibles up to 1250 °C led to big black single crystals of Ba4Sm4Zn3P t0 15. The new compound crystallizes with hexagonal symmetry, space group C^-Pö^mc, a = 1 L657, c = 6,789 A , Z = 2. It is isotypic with Ba6Nd2Al4O l5 but shows an ordered Pt4+ and Zn2+ distribution over the aluminium positions. The octahedrally coordinated barium sites of the Ba6Nd2Al40 15 type are occupied by Sm3+. In comparison to compounds of the composition Ba6Ln2M40 15 (M = Al, Fe, Co), Ba4Sm4Zn3PtOi5 is the first example containing different oxidation states at the M '+ positions.

 Abstract    Reactions of B aC 03, ZnO, Lu20 3 and A120 3 mixtures at temperatures up to 1500 °C led to small and colourless rods of BaLuAlZn30 7. The new compound crystallizes with hexagonal symmetry, space group CöV -P63mc, a = 6.273, c =10.161 A, Z = 2. In spite of small differences in the oxygen content BaLuAlZn30 7 is isotypic to Ba2Ln2Zn80 13. The crystal structure shows Zn2+ with tetrahedral, Lu '+ with octahedral and Ba:+ with anticuboctahedral coordination by 0 2~. It has been shown that parts of the [Zn3A107]5_ network are fragments of the ZnO structure. In consequence one oxygen atom is fourfold coordinated by zinc/aluminium. The space group of Ba2Ln2ZnxO i3 must be corrected to C6V -P63mc.

 Title    Electrochemistry of Oxygenation Catalysts, Part 6* Electrosynthesis, Structure, Analytical and Electrochemical Properties of Monomeric [Coin(salen)(DMF)2]+ X' Salts (X = PF6, C104)  
 Abstract    Electrochemistry [CoH1(salen)(DMF)2]+ X" salts [X = PF6, C104; salen = bis(salicyliden)ethylendiiminato; DMF = dimethylformamide] have been synthesized by electrochemical and chemical (air) oxidation of Co"(salen). Their monomeric structure with two DMF molecules in the axial positions in both the solid state and DMF solution is shown by X-ray crystal structure analysis, thermal analysis, mass spectroscopy, and 'H and l3C NMR spectroscopy. The electrochemical reduction of the [Coni(salen)(DMF)2]+ cation is investigated by cyclic voltammetry and com­ pared to the oxidation of the neutral CoH(salen). The redox reaction connecting the cobalt(II) and the cobalt(III) species appears to be a quasi-reversible electron transfer. These properties make the [Co1 1 (salen)(DMF)2]+ X-salts starting materials for the analysis of the interaction of basic substrates with cobalt(III) species in the context of the biomimetic oxygenation reactions catalyzed by such complexes.

 Title     
 Abstract    Single crystals of BaCuTe03T e 0 4 have been prepared by crystallisation from melts. X-ray investigations lead to orthorhombic symmetry, space group C2v-Ama2, a = 5.4869(8), b = 15.412(1), c = 7.2066(4) A , Z = 4. This compound represents a new structure type, containing B aO 10, C u 0 5, T e 0 6 and T e 0 4 polyhedra. The lone pair (E) of TeIV completes the TeIV0 4 polyhedron to a trigonal T e 0 4E bipyramid. The Te to E distance is estimated by calculations o f the Coulomb terms of lattice energy to 1.43 A .

 Title    Synthesis and Crystal Chemistry o f the /3-Form o f a M ixed Zinc Orthoarsenate  
 Abstract    Single crystals o f Zn228M g0 72(A s 0 4) 2 have been prepared by C 0 2 L A S E R techniques. The compound crystallizes with monoclinic symmetry space group C 2h-P2j/n and the lattice parameters a = 5.292(2), b = 8.450(3), c = 7.737(3) Ä , ß = 96.33(3)°, Z = 2. Zn2 28M g072(A s O 4) 2 is isotypic to /3-Zn3(A s 0 4)2. The formation of the /3-Zn3(A s 0 4) 2 struc­ ture instead o f other possible orthoarsenates is discussed.

 Title    K + auf einer mit C a2+ unterbesetzten Punktlage in Ca3( V 0 4) 2: Ein Beitrag über K C a 10V 7O 28 K + at an D eficient Ca2+ Point Position in C a3( V 0 4) 2: On K C a 10V 7O 28  
 Abstract    Single crystals o f K C a ^ V y O ,« have been prepared by crystallization from flux. The yellow-green crystals show rhombohedral symmetry (trigonal space group C3V-R3c, a = 10.830(1), c = 37.860(1) A , Z = 6). The differences o f the crystal chemistry are discussed with respect to the isotypic compound Ca3(V 0 4) 2. K + replaces exclusively Ca2+ ions at one deficient point position.
