Abstract
The tungsten(VI)diolato complex, [W(eg)(pin)(2)] (H(2)eg = 1,2-ethaned iol, H(2)pin = 2,3-dimethyl-2,3-butanediol) forms adducts with phenol and aniline. X-ray structural studies and spectral measurements (UV an d IR) show that the formation of those adducts is due to hydrogen bond ing between OH or NH2 groups of adductant and diolato oxygen atoms. Th e effect of hydrogen bonding on the octahedral WO6 centre is minimal, but the conformation angles of the five-membered chelate ring change c onsiderably. Hydrogen bonding does not promote alcoholato exchange rea ctions.
