Deskripsi
The title compound, [Co(C14H14Cl)(C4H6N2O2)2(C5H5N)], is a model compound for the more complex cobalamines like vitamins B12. The CoIII atom is coordinated by a (4′-chloromethyl-[1,1′-biphenyl]-4-yl)methyl group, an N-bonded pyridine and two N,N′-bidentate dimethylglyoximate ligands in a distorted octahedral geometry. The glyoximate ligands exhibit intramolecular O—H...O hydrogen bonds, which is very common in cobaloxime derivatives.
