Über Chalkogenolate. 98 [1]. Kristall- und Molekülstruktur von Wolfram(IV)-äthylthioxanthat

On Chalcogenolates. 98. Crystal and Molecular Structure of Tungsten(IV) Ethylthioxanthate WS₂C? SC₂H₅]₄ crystallizes with Z = 2 in the tetragonal space group P4₂/n with cell dimensions a = 11.108(5) Å and c = 9.489(5) Å. The crystal and molecular structure has been determined from single crystal X-ray data at ?160°C and refined to a conventional R of 0.058. The structure consists of isolated molecules. The tungsten atom is bonded to eight sulfur atoms from four chelating thioxanthate ligands. The coordination geometry approximates very closely to triangularly dodecahedral.
