The crystal structure determination of the title compound, a model for coenzyme B12, indicates that it is [Co(C4H6N2O2)(C5H 9)(C4H8N2O2)(H 2O)], i.e. one 2,3-butanedione dioxime ligand is neutral and the second is a dianion, with the CoIII ion in a distorted octahedral environment. The axial Co-C bond length [2.029 (2) Å] is close to that of coenzyme B12 [2.00 (1) Å].
