Bis(5-penta-methyl-cyclo-penta-dien-yl)cobalt(II)

Abstract

The crystal structure of the title compound, deca-methyl-cobaltocene, [Co(C10H15)2], has been determined. High-quality single crystals were grown from a cold saturated hexa-methyl-disiloxane 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.
