title: Penta-carbon-yl(imidazolidine-2-thione-κS)tungsten(0).
abstract: In the title complex, [W(C(3)H(6)N(2)S)(CO)(5)], the W atom displays an octa-hedral coordination with five CO mol-ecules and an imidazolidine-2-thione mol-ecule. The W(CO)(5) unit is coordinated by the cyclic thione ligand through a W-S dative bond. The W-S and C-S bond lengths are 2.599 (2) and 1.711 (9) Å, respectively. This last distance is significantly longer than that of free cyclic thio-ureas. The geometry of the title compound suggests sp(3)-hybridization of the S atom caused by the greatly polarized linkage W-S-C bond angle, which is close to tetra-hedral [109.50 (3)°]. In the crystal packing, N-H⋯O and N-H⋯S hydrogen-bonding inter-actions stabilize the structure and build up chains parallel to [101].
