2012    Kumar, Sarvendra; Thapa, Suresh

In the title compound, [Co(C4H9)(C4H7N2O2)(2)(C5H5N)], which was prepared as a model complex of vitamin B-12, the Co-III atom is coordinated by a butyl group, a pyridine and two N,N'-bidentate dimethylglyoximate ligands in a distorted octahedral geometry. The bis-chelating dimethylglyoximate ligands, which occupy equatorial sites, are linked by strong intramolecular O-H center dot center dot center dot O hydrogen bonds.
