 Title    Synthese und Kristallstruktur von C83(AuBr 4 ) 2 Br3 Synthesis and Crystal Structure of Cs3(AuBr4) 2 Br 3  
 Abstract    Cs3(AuBr4)2Br3 is obtained in the form of red needles by adding the stoichiometric amount of CsBr to a solution of HAuBr4 and Br3~ in aqueous HBr. The salt decomposes slowly at room temperature to form a mixed-valent, cubic bromo aurate(I,III), in which the linear AuBr 2 ~ ions are partially substituted by Br3~ ions. At 140 °C Cs 2 Au 2 Bre and CsBr are formed. Cs3(AuBr4) 2 Br3 crystallizes monoclinic with four formula units in the space group P2i/c. The structure is built up by AuBr 4 ~ and Br3~ anions and Cs+ cations. An average Au-Br distance of 242.2 pm was found for the square planar AuBr 4 ~ ion. The linear Br3~ groups are almost symmetrical with Br-Br distances of 254.0 and 256.2 pm. Therefore only two vibrations are observed in the IR spectrum: Vas = 172, <5 = 56 cm -1 . The absorptions of the AuBr 4 _ groups are: vas = 250, <5as= 113, y — 102 cm -1 .

 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.

 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.
