| Thio-hydroxoanionen des Germaniums: Darstellung, Struktur und Eigenschaften von Na2GeS2(OH)2 * 5 H20 Thio-hydroxo Anions of Germanium: Preparation, Structure and Properties of Na2GeS2(OH)2 * 5 H20  | | | | Abstract
| Pure thio-hydroxo-germanates can be prepared from aqueous solutions by reactions of stoichiometric amounts of either sodium sulfide and Ge02, or NaOH and GeS2. The preparation of colourless crystalline Na2GeS2(OH)2 • 5 H20 is reported. The compound is characterized by a single-crystal X-ray structure analysis. It is orthorhombic, space group Pbcn, with a = 10.752(2), 6= 13.787(2), c = 14.150(2) A. The structure contains novel monomeric GeS2(OH)2 2-anions with Ge-S bond distances of 2.150(1) and 2.145(1) Ä and with Ge-0 lengths of 1.809(3) and 1.815(3) A. An extensive S • • • HO-and O -HO-hydrogen bond system connects the anions with the octahedrally coordinated Na + ions. The vibra-tional spectra are reported. The symmetric GeS2 andGe02 stretching vibrations in the anion are observed at 415 and 618 cm -1 . | | | |
