The tetramethylethylene-bridged chromocene carbonyl complex (CH<sub>3</sub>)<sub>4</sub>-C<sub>2</sub>(C<sub>5</sub>H<sub>4</sub>)<sub>2</sub>Cr(CO) is obtained by reaction of the Grignard compound (CH<sub>3</sub>)<sub>4</sub>-C<sub>2</sub>(C<sub>5</sub>H<sub>4</sub>MgCl)<sub>2</sub>·4THF with CrCl<sub>2</sub>·THF Under CO. The diamagnetic carbonyl complex is the first thermally stable chromocene ligand adduct; its structure is that of a normal wedge-shaped metallocene derivative whose ring ligands span a centroid-chromium-centroid angle of 143°; the molecule closely approximates to C<sub>2</sub> symmetry with respect to the Cr-C≡O axis. eng ansa-metallocene derivatives : VI.
