The novel oxo-centred tetrahedral cobalt duster [Co4O](6+) bridged by
six carbamato ligands is prepared in high yield when reacting [Co-2(CO
)(8)] with an excess of the nitroxyl radical 2,2,6,6-tetramethylpiperi
din-1-oxyl; the molecular structure of the title compound is determine
d by a single-crystal X-ray analysis.
