| 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 . | | |

| 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. | | |

| 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. | | |

| 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. | | |
