title: Chloridobis(dimethyl-glyoximato-κN,N')(4-methyl-pyridine-κN)cobalt(III) hemihydrate.
abstract: In the title complex, [Co(C(4)H(7)N(2)O(2))(2)Cl(C(6)H(7)N)]·0.5H(2)O, the central Co(III) ion, chelated by four N atoms of the two bidenate glyoximate ligands, exhibits a slightly distorted octa-hedral geometry. The axial positions are occupied by a chloride ion and the 4-methyl-pyridine N atom. Inter-molecular O-H⋯O hydrogen bonds link the mol-ecules in the crystal via the water mol-ecules, while the glyoximate ligands exhibit intra-molecular O-H⋯O hydrogen bonds.
