metal-organic compounds
Development of a reproducible synthesis of (η6-benzene)tricarbonyltungsten, by photolysis of [W(CO)6] has allowed the preparation of crystalline samples suitable for diffraction analysis. The material is isomorphous with [Cr(η6-C6H6)(CO)3] and [Mo(η6-C6H6)(CO)3], with the benzene ligand staggered with respect to the W(CO)3 group. The benzene ligand exhibits bond-length alternation similar to that observed for the Cr and Mo complexes [average C—C short bond 1.397 (10) Å, average C—C long bond 1.424 (10) Å], and bond lengths to W are similar to bond lengths to Mo in [Mo(η6-C6H6)(CO)3] [W—CAr bonds range from 2.353 (5) to 2.375 (5) Å].
