M. M. Clark, W. W. Brennessel and P. L. Holland

Abstract: The crystal structure of the title compound, decamethylcobaltocene, [Co(C₁₀H₁₅)₂], has been determined. High-quality single crystals were grown from a cold saturated hexamethyldisiloxane solution. The structure is related to the manganese and iron analogs. The molecule has D_5d symmetry, with the Co atom in a crystallographic 2/m position. The cobalt-centroid(C₅) distance is 1.71Å and the centroid(C₅)-Co-centroid(C₅) angle is 180°, by symmetry.
