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