| Title | Rb6In2S6 und Rb4In2S5, zwei neue Thioindate mit isolierten und verknüpften [In2S6] fi ~ Anionen Rbßl^Se and Rb4ln2Ss, Two NEW Thioindates with Isolated and Connected [I^Se] 6-Anions Respectively  | ||
| Abstract | The hitherto unknown title compounds were prepared by a disproportionation reaction starting from elementary rubidium and indium monosulfide. Rb4ln2Ss crystallizes in the triclinic system (P 1) with the lattice constants a = 931.7(2); d> = 1097.6(3);c = 761.2(2)pm; a = 111.32°(2); ß = 94.70°(2); y = 103.70°(2) (Z = 2) and Rb6In2S6 in the monoclinic system (C2/m) with the lattice constants a = 895.3(2); b = 1356.9(2); c = 791.8(2) pm; ß = 101.53°(2) (Z = 2). The quasi molecular [I^Se] 6-group which is isoelectronic with the gas phase molecule I^Clg consists of two edge sharing InS4 tetrahedra and is the basic unit of Rb4ln2Sö as well as of RbgL^Se. The formation process, structural relationships between the two compounds and their possible role in the phase diagram of the components Rb2S and L12S3 are discussed. | ||
