Synthesis and characterization of 6,7 and 8-coordinate monomeric complexes of tungsten obtained from reaction of [W(CO)3(MeCN)3] with pyridine-2-thiol (pySH) and PPh3

Complexes [W(CO)4(PPh3)2] 1, [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 (pySH) 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.
