Zusammenfassung

The tetramethylethylene-bridged chromocene carbonyl complex (CH3)4-C2(C5H4)2Cr(CO) is obtained by reaction of the Grignard compound (CH3)4-C2(C5H4MgCl)2·4THF with CrCl2·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 C2 symmetry with respect to the Cr-C≡O axis.
