Chloridobis(dimethylglyoximato-κ²N,N′)(4-methylpyridine-κN)cobalt(III) hemihydrate

Abstract

In the title complex, [Co(C4H7N2O2)2Cl(C6H7N)]·0.5H2O, the central CoIII ion, chelated by four N atoms of the two bidenate glyoximate ligands, exhibits a slightly distorted octa­hedral geometry. The axial positions are occupied by a chloride ion and the 4-methyl­pyridine N atom. Inter­molecular O—H⋯O hydrogen bonds link the mol­ecules in the crystal via the water mol­ecules, while the glyoximate ligands exhibit intra­molecular O—H⋯O hydrogen bonds.
