	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.

	Title	Strukturisomere von Kupfer(I)iodid * Pyridin und ihre Lumineszenzeigenschaften. 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.

	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	Polymere Dimethyl-und Diphenylglyoximatokomplexe des Cobalts und Eisens mit Pyrazin als Brückenligand. Die Kristallstruktur des Bis(dimethylglyoximato)pyrazin-cobalt(II) + Polymeric Dimethyl-and Diphenylglyoximato Complexes of Cobalt and Iron with Pyrazine as a Bridging Ligand. The Crystal Structure of Bis(dimethylglyoximato)pyrazine Cobalt(II)+
	Abstract	Polymeric bis(dimethyl-and diphenylglyoximato)-complexes of Fe(II) and Co(II) with pyrazine as a bridging ligand have been synthesized. The Co(II) complexes are para-magnetic with n = 1.83 B.M., and surprisingly stable against oxidation. Bis (dimethyl-glyoximato)pyrazine-cobalt (II) crystallizes monoclinic in the space group C2/m with Z = 2. The crystal structure shows linear chains of alternating Co atoms and pyrazine ligands. Perpendicular to the chain, the Co atoms are coordinated in a square planar arrangement by two dimethylglyoximato ligands (Co-N= 189 pm), the local symmetry being C2h-The long Co-pyrazine distance of 224 pm is in agreement with the fact that the compound is a 19 electron complex. The Co complexes do not have conducting properties. The Fe(II) complexes possess the same structure but with stronger bonds in the chain. They show very low conductivity of approximately 10 -10 cm -1 Q~ l . The Mössbauer spectra of the Fe-complexes are reported.

	Abstract	(2) with three P 111 and one P v , and (3) with two P In and P v atoms are prepared from 1 with methyl iodide. NMR spectra of 2 are compared with those of the recently prepared [1] 4. The crystal structure of 3 shows the molecule to have a crystallographic inversion centre. Thus cis-trans isomerisation must have taken place during the working up procedure. Alkylation has severe consequences on bond distances and bond angles of the cyclotetraphosphazane ring system, in contrast to M(CO)s complexation at the same positions as shown in a similar case recently [8].

	Title	Nitrido-azido-Komplexe des Molybdäns(VI) Synthese und Kristallstruktur von MoN(N3)3(NC5H5) Nitrido Azido Complexes of Molybdenum (VI) Synthesis and Crystal Structure of MoN(N3)3(NC5H5)
	Abstract	The explosive nitrido azido complexes MoN(N3)Cl2 • py and MoN(N3)3py are prepared by the reaction of MoCLi(py)2 with (CH3)3SiN3 in 1,2-dichloroethane. Both compounds hydrolyze quickly in moist air. After separation of the insoluble, black MoN(N3)Cl2 • py from the solution of MoN(N3)3py, the latter can be obtained in form of monoclinic, red crystals of the space group C2/c. Its structure consists of monomeric complexes, wherein the Mo atom has a square pyramidal coordination. The nitrido ligand occupies the apex and forms a strong multiple bond of 163.4 pm to the Mo atom. cr-Bonds of different strength exist between the Mo atom and the basal ligands: M0-N3 — 204.3 pm; Mo-py = 225.8 pm. The a-N atoms of the azido groups are sp 2 hybridized, with their lone pair pointing away from the nitrido ligand. The pyridine ligand forms an angle of 61.6° to the basal plane of the coordination polyhedron.

	Title	Tl2Sn2S5, a Thallium(I) Thiostannate(IV) with Fivefold Coordinated Tin
	Abstract	The new compound Tl2Sn2Ss was prepared by fusion of a stoichiometric mixture of the elements followed by prolonged heating at 300 °C. The compound crystallizes in the monoclinic system in space group C2/c with lattice constants a — 11.115(2), 6 = 7.723(1), c = 11.492(2) A, and ß = 108.60(1)° (Z = 4). The Sn atoms are coordinated by five S atoms forming a considerably distorted trigonal bipyramid (mean distance Sn-S: 2.497 Ä). By common edges the SnSö bipyramids are linked into chains extending in the [110] and [1T0] directions, respectively. The chains are cross-linked by sharing the remaining equatorial vertices of the SnSs bipyramids, thus forming a three-dimensional framework which is related to that described for NajS^Sg [1]. The T1 atoms located in channels running parallel to the b axis are surrounded by nine S atoms. The distances Tl-S vary from 3.073 to 3.897 A.

	Abstract	1,2 A 3 ,3 A 3 -Azadiphosphiridines are avaüable by elimination of hydrogenhalide from ß-and y-functional molecular frameworks and by 1 + 2 cycloaddition of phosphinidenes towards aminoiminophosphanes. In contrast to other three-membered phosphorus com-pounds, azadiphosphiridines decompose by 2 +1 cycloreversion to aminoiminophosphanes and phosphinidenes. The molecular structure of an azadiphosphiridine demonstrates the trans arrangement of the exocyclic ligands and the planarity of the endocyclic nitrogen.
