Abstract
The germanium chalcogenolates (PhSe)4Ge and (PhTe)4Ge were synthesized from activated hydrogenated germanium (Ge*) and diphenyldiselenide or diphenylditelluride, respectively. (PhTe)4Ge is the first homoleptic organotellurolate of germanium. It was characterized spectroscopically and by X‐ray crystal structure analysis. (PhTe)4Ge crystallizes in the monoclinic space group P21/c with a = 12.8018(14), b = 9.1842(9), c = 23.690(3) Å and β = 105.458(8)°. The molecules show a tetrahedral GeTe4 core. Weak Te‐Te interactions connect neighbouring tetrahedra to infinite helices along [010]. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)Keywords
