The structures of the μ 3 -ethylidyne tricobalt clusters Cp* 3 CO 3 (μ 3 -CCH 3 ) 2 (2) and Cp* 3 Co 3 (μ 3 -CCH 3 )(μ 3 -H) (3) were determined by X-ray crystallography. The 48-electron cluster 2 consists of an equilateral triangle of cobalt atoms (Co‒Co = 2.437(1) Å) symmetrically capped on each face by a μ 3 -CCH 3 ligand. Cluster 3 was necessarily disordered by the crystallographic site symmetry (3/m) and was therefore refined by employing a mirror-disordered model (3a) which assigned half-weight to the disordered μ 3 -CCH 3 ligand. The 46-electron cluster 3a consists of an equilateral triangle of cobalt atoms (Co‒Co = 2.378(1) Å) symmetrically capped on a single face by a μ 3 -CCH 3 ligand. © 1994, American Chemical Society.
