Abstract: | On Chalcogenolates. 98. Crystal and Molecular Structure of Tungsten(IV) Ethylthioxanthate W[S2C? 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. |
