 Title    Darstellung und Charakterisierung von Sulfinatokomplexen 7r-C7H7Mo(C0)2S02R (R=-C6H5, -C6H4CH3) sowie von ein-und zweikernigen Thioarylverbindungen der Zusammensetzung 7r-C7H7Mo(CO)2SR' bzw. [^-C7H7Mo(CO)SR ]2 (R =-S-C6H5, -S-C6H4CH3, -S-C6F5, -S-C6H4N02)  
 Abstract    Synthesis and Characterization of Sulfinato Complexes 7r-C7H7Mo(C0)2S02R (R = -C6H5, -C6H4CH3) and of Mono and Dinuclear Thioaryl Compounds of Composition TT-C7H7MO(CO)2SR' resp. 0t-C7H7Mo(CO)SR']2 (R' = The aryl-sulfinato complexes ?r-C7H7Mo(CO)2S02R have been synthesized by re-action of JI-C7H7MO(CO)2J with the Ag-SC>2-R compounds. The sulfinate group is S-bonded. Mononuclear and dinuclear thioaryl complexes were isolated by reaction of 7r-C7H7Mo(CO)2Br with aryl mercaptanes R'-S-H in the presence of (CaHs^N which functioned as a proton acceptor. IR data indicate the dependence of the 7t-acceptor abilities of the sulfur atom from R'. Der Sulfinatrest -SO2-R kann sowohl als ein-zähniger als auch als zweizähniger Ligand fungieren. Als einzähniger Ligand kann er sowohl über das Schwefelatom (Sulfinato-S-Komplex) als auch über ein Sauerstoffatom (Sulfinato-O-Komplexe) gebun-den sein 1 . 0 0 0 0—s—0 II II /\ / \-o 7 Als zweizähniger Ligand ist die R-SCVGruppe intra-bzw. intermolekular an das Zentralatom koordiniert 1 . Die Darstellung der Sulfinatokomplexe gelingt im allgemeinen durch direkte Einschiebung von SO2 in eine Metall-Kohlenstoffbindung z.B. gemäß 2 -3 :

 Title    KLAUS-JÜRGEN RANGE  
 Abstract    Manganese MnGa2Se4 and MnGa2Te4 were prepared by direct synthesis from the elements at 900-1000 °C. MnGa2Se4 (Space group l!, a = 5.676(2) A, c = 10.760(3) A, z = 2) is iso-typic with CdGa2S4.

 Title    ZrSi04 mit monokliner Baddeleyitstruktur ? ZrSi04 with Monoclinic Baddeleyite Structure ?  
 Abstract    A new compound having the same composition as zircon, ZrSiC>4, but differing from it in its structure has been obtained by heating zircon particles to a temperature of 5000 to 10000 °K. According to X-ray powder diffraction data the structure and within limits of error also the unit-cell dimensions are identical with that of monoclinic baddeleyite, Zr02. This suggests that the baddeleyite lattice can not only accommodate 10 molecular % Si02 as is already known for some time, but substantially more, unless it is assumed that some kind of submicroscopic exsolution of amorphous Si02 has taken place.

 Title    Tetrahalogeno -acetylacetonato -osmate (IV) Tetrahalogeno-acetylacetonato-osmates(IV)  
 Abstract    The complexes K[OsX4acac], X = Cl, Br, I, are prepared by treatment of K^fOsXß] with acetylacetone. The new compounds are characterized by their IR resp. visible and UV spectra which are highly resolved when measured on transparent pellets of the tetra-ethylammonium salts with KBr at 10 K. The influence of the different halide ligands on the bonding of the acac-group is discussed.
