摘要
Racemic 6,6'-disubstituted-1,1'-bi-2-naphthols H(2)X(2)bino (X = H, Br) and corresponding binaphthyl acetates react with trisdiolatetungsten(VI) complexes [W(eg)(3)] and [W(eg)(pin)(2)] (eg = ethanediolate dianion, pin = pinacolate dianion) forming heteroleptic complexes [W(X(2)bino)(diolato)(2)]. The X-ray crystal structure determinations confirmed that the isolated compounds are made of monomeric tris(diolate)tungsten(VI) molecules in which the central tungsten atom is bonded to six oxygen atoms forming a distorted octahedral coordination sphere around the metal ion.
