	Title	Synthese und Kristallstruktur eines Triazido-nitrido-bipyridyl-Komplexes des Molybdäns(VI): MoN(N3)3(bipy) Synthesis and Crystal Structure of a Triazido Nitrido Bipyridyle Complex of Molybdenum(VI): MoN(N3)3(bipy)
	Abstract	The reaction of MoCl^bipy) with an excess of (CH3)3SiN3 in 1,2-dichloroethane results in the formation of a mixture of MoN(N3)3(bipy) and Mo(N2)Cl2(bipy). The latter is an insoluble, brownish compound of yet unknown structure. MoN(N3)3(bipy) is very soluble in 1,2-dichloroethane and easily hydrolysed. It can be crystallized from toluene in the form of explosive, red crystals of the space group P 2i\n. The crystal structure is built up by monomeric complexes, in which the Mo atom has a distorted sixfold coordination. The three azido groups are located eis to the nitrido ligand, with their free electron pair at the a-N-atom pointing away from the closely neighbouring nitrido ligand. The bipyridine forms two bonds of quite different length (224,0 and 241,9 pm) with the Mo atom, as trans to the triply bounded nitrido ligand (Mo = N = 164,2 pm) only a weak interaction is possible.

Darstellung und Kristallstruktur einer neuen Modifikation von Cul * NC5H5 Structural Isomers of Copper(I) Iodide Pyridine and their Luminescence Properties Synthesis and Crystal Structure of a New Modification of Cul * NC5H5
	Abstract	A new modification of Cul • py was prepared by the reaction of a saturated solution of Cul in CH3CN with a solution of pyridine in ethanol at 60 °C. It crystallizes mono-clinic with four formula units in the space group P2i/c. (Cul • py)oo forms a polymeric ribbon structure. Contrary to the cubane-like tetrameric modification, (Cul • py)oo does not show luminescence thermochromism. The luminescence properties of both modifications of Cul • py are interpreted.

	Title	Ringkontraktion am Cyclotrisilazan -System - Synthese und Molekülstrukturen zweifach silylverknüpfter Cyclodisilazane Ring Contraction in the Cyclotrisilazane System - Synthesis and Molecular Structures of Silyl-Bridged Cyclodisilazanes
	Abstract	l-(Fluorodiorganylsilyl)-2,2,4,4,6,6-hexamethyl-3-(trimethylsilyl)cyclotrisilazanes react with butyllithium to give the corresponding lithium salts. Ring contraction of the lithium salts with formation of lithiated (fluorodiorganylsilyl)amino-substituted four-membered rings is observed in THF solution. The dimerisation of these cyclodisilazanes with elimina-tion of LiF is demonstrated by crystal structure determinations of three products. Monoclinic and triclinic crystalline modifications of one compound could be isolated.

	Abstract	The crystal structure of the complex compound of SbCL with a chelating bipyridyl group was determined. Sb(CioH8N2)Cl3 crystallizes in the space group P2i/c with a = 818.9(4), b = 695.8(7), c = 2331.3(12) pm, ß = 103.59(4)° and Z = 4 molecules per unit cell. The SbCL fragment is T-shaped with <Sb-Cl> at 254.7 pm. Taking into account also the N atoms of the chelating 2,2'-bipyridyl group (<Sb-N> = 228.1 pm) and an inter-molecular Sb-Cl contact at 334.0 pm the Sb coordination is distorted octahedral.

	Title	Ternäre Gamma-Messing Phasen in den Systemen Calcium-M IB(IIB) -Quecksilber New Ternary Gamma-Brass Phases in the Systems Ca-M iB(nB)_Hg
	Abstract	A series of new ternary intermetallic com-pounds of the general composition CaißMi8IB(IlB)_Hg18 (M = Zn, Cd, Hg, Cu, Ag and Au) has been identified. The X-ray powder diffraction patterns were indexed on a basis of primitive cubic unit cells. From the X-ray data and density measure-ments it is concluded that these phases belong to the partially disordered (Ml B (HB) and Hg) gamma-brass structure type D83.

	Title	B. Krebs-D. Sinram * Darstellung, Struktur und Eigenschaften einer neuen Modifikation von Nbls 20 Preparation, Structure and Properties of a New Modification of Nbls
	Abstract	Triclinic niobium(V) iodide was prepared from the elements at an iodine pressure of 3-4 bar in a temperature gradient from 400 to 230 °C. It crystallizes in the space group PI with a = 7.591(3), b = 10,322(3), c = 6.977(3) A, a = 90.93(3), ß = 116.17(3), y = 109.07(3)°, Z = 2 Nbls. The single-crystal X-ray structure analysis shows the compound to contain dimeric Nb2lio molecules with Nb-I bond lengths of 2.933 and 2.939(1) A for the bridge bonds and of 2.639 • • • 2.720(1) A for the terminal bonds. The structure is isotypic with triclinic /S-UCI5. The infrared spectrum indicates stretching vibrations at 148, 202, 214 and 242 cm-1 .

	Abstract	1-Methyl-, 1-ethyl-, 1,2-dimethyl-and 1,2,3,4-tetramethylimidazole react with penta-carbonyliron to yield [FeIm6][Fe(CO)8] (1), [FeIm6][Fe(CO)4]2 (2), [FeIm4][Fe(CO)4] (3) and Fe(Im)(CO)2 (4) (Im = substituted imidazole). The crystal and molecular structures of 1 and 2 have been determined by X-ray diffraction. For 1 and 2 agreement between calculated and measured Mössbauer absorption intensities was obtained by taking into account Debye-Waller-factors, which were derived from the X-ray diffraction experiments.

The structures of the cubic phases Na2HgSn, Na2CdPb and Na2HgPb (space group F43m) are closely related to LiaBi, that of Na2CdSn (space group P63mmc) to the hexagonal structure of NaßAs.

	Abstract	The hitherto unknown title compounds were prepared by a disproportionation reaction starting from elementary rubidium and indium monosulfide. Rb4ln2Ss crystallizes in the triclinic system (P 1) with the lattice constants a = 931.7(2); d> = 1097.6(3);c = 761.2(2)pm; a = 111.32°(2); ß = 94.70°(2); y = 103.70°(2) (Z = 2) and Rb6In2S6 in the monoclinic system (C2/m) with the lattice constants a = 895.3(2); b = 1356.9(2); c = 791.8(2) pm; ß = 101.53°(2) (Z = 2). The quasi molecular [I^Se] 6-group which is isoelectronic with the gas phase molecule I^Clg consists of two edge sharing InS4 tetrahedra and is the basic unit of Rb4ln2Sö as well as of RbgL^Se. The formation process, structural relationships between the two compounds and their possible role in the phase diagram of the components Rb2S and L12S3 are discussed.

	Title	Tetrazido-Nitrido-Molybdat(VI); Darstellung, IR-Spektrum und Kristallstruktur von AsPh4[MoN(N3)4] Tetrazido-nitrido-molybdate(VI); Preparation, IR Spectrum and Crystal Structure of AsPh4[MoN(N3)4]
	Abstract	The complex AsPh4[MoN(N3)4] is prepared by the reaction of AsPh4[MoNCl4] with silver azide in dichloromethane suspension in the presence of dry sodium sulfate. The IR spectrum indicates an Mo=N group and four covalently bonded N3 groups for the [MoN(N3)4] e anion. AsPh4[MoN(N3)4] crystallizes in the triclinic space group P1 with two formula units in the unit cell. The crystal structure was solved by X-ray diffraction methods (R = 0,038; 4049 independent reflexions). The structure consists of AsPh4® cations and [MoN(N3)4] e anions. The short MoN bond length of the nitrido ligand (163 pm) corresponds to an Mo = N triple bond. The steric effects of the lone pairs of the a-N atoms of the azido groups with the MoN ligand cause a propellerlike twisted conformation of the four azido groups.
