Abstract
A second, trigonal, phase of [CCo3(CO)9]2, ppa3C1;4:5:6kappa3C2-hexaki s(tricarbonylcobalt)-(6 Co-Co), has been found, in addition to the mon oclinic one reported earlier [Brice & Penfold (1972). Inorg. Chem. 11, 1381-1384]. The intermolecular geometry of the molecule in the two cr ystallographic modifications is virtually the same. The two Co3 triang les are twisted by ca 28-degrees with respect to each other, indicatin g a conformation between staggered and eclipsed. Optically active crys tals of the trigonal phase form by spontaneous resolution of the enant iomorphic conformers.
