Six-co-ordinate 1,2-dithiolene complexes of tungsten(II) of the type [W(S–S)(CO)2L2] [S–S = C3S5, benzene-1,2-dithiolate or maleonitriledithiolate; L2 = (PPh3)2, (PEt3)2 or Ph2P(CH2)2PPh2]

Abstract

Reaction of the complexes [WI2(CO)3L2] [L2 = (PEt3)2, (PPh3)2 or Ph2P(CH2)2PPh2 = dppe] with 1 equivalent of Na2[S–S] (S–S = C3S5 or maleonitriledithiolate) or H2bdt (benzene-1,2-dithiol) in acetonitrile and ethanol at room temperature afforded good yields of the six-co-ordinate compounds [W(S–S)(CO)2L2] by displacement of the iodide ligands and a carbonyl ligand. X-Ray crystallographic studies were carried out on [W(S–S)(CO)2L2] [S–S = C3S5, L2 = (PEt3)2; S–S = bdt, L2 = (PEt3)2 or L2 = dppe]. The three structures are all six-co-ordinate with geometries intermediate between octahedral and trigonal prismatic but closer to the latter.
