Abstract: Complexes [W(CO)4(PPh3)21, [W(CO)4(pySH)( PPh3)] 2, [W(CO)2(pyS)2(PPh3)] 3 and [W(PyS)4] 4 have been obtained from the reaction of [W(CO)3(MeCN)3] with pyridine-2- thiol (py SH) and PPh3 in refluxing THF. 1 and 2 are normal 6-coordinate complexes but 3 and 4 are unusual 7 and 8- coordinate complexes, respectively. The complexes have been characterized by IR, 1H and 31P{1H}NMR, mass spectra and elemental analysis.
