The title compound, trans-[Co(C(4)H(7)N(2)O(2))(2)Cl(C(10)H(14)N(2)S)]·0.5H(2)O, contains two independent mol-ecules in the asymmetric unit in which the Co(III) ions are coordinated in slightly distorted octa-hedral coordination environments. The bis-chelating glyoximate ligands, which occupy equatorial sites, are linked by interligand O-H⋯O hydrogen bonds. The dihedral angles between the mean ...
