Neutral tungsten(VI) complexes [W(eg) (pin)2] (2) and [W(pin)3] (3) (eg = 1,2-ethanediolato ligand, pin = 2,3-dimethyl-2,3-butanediolato ligand) were prepared from [W(eg)3] (1) and H2pin by a diol exchange reaction. The X-ray crystalstructures of the compounds were determined. In both complexes, the central tungsten atom of the monomer is octahedrally coordinated by six oxygen atoms of three diolato
