Dichlorido(dimethylglyoximato-κ2N,N′)(dimethylglyoxime-κ2N,N′)cobalt(III)

Abstract

In the title compound, [Co(C4H7N2O2)Cl2(C4H8N2O2)], the CoIII ion has a distorted octahedral coordination environment. The equatorial plane consists of four N atoms, two each from the dimethylglyoxime and dimethylglyoximate ligands, while the two axial positions are occupied by two chloride ions. Strong intramolecular O—H...O hydrogen bonds are observed between the dimethylglyoxime and dimethylglyoximate ligands. Molecules are linked into a chain running along the [101] direction by O—H...O and C—H...Cl hydrogen bonds. The chains are cross-linked through intermolecular C—H...Cl hydrogen bonds.
