Chloridobis(dimethyl-glyoximato-κN,N')(ethyl pyridine-4-carboxyl-ate-κN)cobalt(III) chloro-form monosolvate.


ABSTRACT: The title compound, [Co(C(4)H(7)N(2)O(2))(2)Cl(C(8)H(9)NO(2))]·CHCl(3), was synthesized as a model complex of vitamin B(12). The Co(III) cation displays an approximately octa-hedral coordination environment, being displaced by 0.0240 (15) Å from the mean plane of the four N atoms of the equatorial plane. The O-H distances in the dimethyl-glyoximate hy-droxy groups are 0.89 (6) and 1.14 (6) Å; such long O-H bonds are very common in cobaloxime derivatives. Weak classical O-H⋯N and non-classical C-H⋯Cl hydrogen-bonding interactions further consolidate the crystal packing.
