Penta­carbon­yl(imidazolidine-2-thione-κS)tungsten(0)

In the title complex, [W(C(3)H(6)N(2)S)(CO)(5)], the W atom displays an octa­hedral coordination with five CO mol­ecules and an imidazolidine-2-thione mol­ecule. 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 thio­ureas. 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 tetra­hedral [109.50 (3)°]. In the crystal packing, N—H⋯O and N—H⋯S hydrogen-bonding inter­actions stabilize the structure and build up chains parallel to [101].
