Crystal and molecular structure of hexakis(tert-butoxo)dialuminum. Comments on the extent of M-O .pi. bonding in Group 6 and Group 13 alkoxides

Transmetallation and oxidative substitution were utilized to prepare examples of group 14, group 6 and group 10 complexes from lithiated or chlorinated 4,4-dimethyl-2-(2-thienyl) oxazoline or its N-alkylated analogs. Two of the product types (2and 5) can be classified as a-thio or remote carbene complexes, depending on the position (3- or 5-) of attachment to the substituted thiophene ring. Spectroscopic measurements as well as crystal and molecular structure determinations clarified the bonding within the new compounds.

Crystals of [Mo(CO)2( dpmSe )2Cl]2 [Mo6O19].4CH3NO2 are triclinic, Pī , a 12.985(3), b 13.981(3), c 17.200(3)Ǻ, α 91.55(2), β 92.00(2), γ 101.12(2)°. In the cation, [Mo(CO)2(dpmSe )2Cl]+, the molybdenum atom is seven-coordinate with a slightly distorted capped octahedral environment. A carbonyl group occupies the capping position, and both dpmSe ligands display bidentate coordination. The dimensions of the anion are very similar to those previously reported.
