Abstract
A tungsten (VI) complex [WCl2(pin)(2)] 1 [H(2)pin = pinacol (2,3-dimethylbutane-2.3-diol)l reacted with water forming dimeric [W2O3(pin)(2)(Hpin)(2)]. but in the presence of tripropylamine [(NPr3H)(2)Cl](2)[W6O19] 2 was formed. The reaction of 1 with H(2)pin led to [W(pin)(3)] and with phenol (PhOH) to [W(pin)(2)(OPh)(2)] 3. The structures of complexes 2 and 3 were confirmed by X-ray methods. Compound 2 is made up of the known [W6O19](2-) anion and two [NPr3H ... Cl-... HNPr3](+) cations. Complex 3 is formed of monomeric [W(pin)(2)(OPh)(2)] molecules in which the W atom is octahedrally surrounded by six oxygen atoms.
