| Ag8GeTe6, ein Vertreter der Argyroditfamilie AgsGeTe6, a Representative of the Argyrodite Family  | | | Abstract
| A single crystal of AgsGeTe6 was found to be rhombohedral, pseudocubic, space group R3m, with a— 817.6 pm, a — 60° and Z — 1. The anion lattice consists of three-dimen-sionally connected Frank-Kasper polyhedra with C. N. 12 and 16. The structure comprises isolated GeTe4-tetrahedra and silver ions, statistically distributed over a number of sites with distorted tetrahedral, trigonal and linear co-ordination. Structural data for some other compounds of the argyrodite family are given. | | |

| Darstellung, Kristallstruktur und Infrarotspektrum von [MONC13 * P0C13]4 Preparation, Crystal Structure and Infrared Spectrum of [MONC13 * P0C13]4  | | | Abstract
| [MoNCl3 • P0C13]4 is prepared both by the reaction of MoNCl3 with POCl3 as well as by the reaction of M0CI5 with NC13 in the presence of P0C13. [MONC13 • P0C13]4 crystallizes in the monoclinic space group P2i/c with 2 tetrameric molecules in the unit cell. The crystal structure was solved by X-ray diffraction methods (R — 0.033, 1821 observed reflections). The structure consists of planar and almost square Mo4N4-eight-membered rings with alternating Mo-N bond lengths. The distorted octahedral environment of the molybdenum atoms is completed by three terminal Cl-ligands and by the oxygen atom of a POCl3 molecule, which is coordinated trans to the Mo = N triple bond. The IR spectrum is discussed with respect to the vibrational spectra of the isoelectronic niobium complex [NbOCl3 • P0C13]4. | | |

From the SH complexes no identifiable products could be obtained. For X = SnMe3, the iodine oxidation of 2 yielded (Me3P)2(CO)5Mn2S2 (5), that of 3 gave (CO)i5Mn4S4 (7), both containing bridging disulfide ligands. The crystal structure of 7 was determined. | | |
