Abstract: In the title complex, [Co(C₂₂H₁₈N₂O₄)(CN)(H₂O)]·0.5CH₃CN, the Co^III cation is N,N',O,O'-chelated by a 6,6'-dimethoxy-2,2'-[1,2-phenylenebis(nitrilomethanylylidene)]diphenolate dianion, and is further coordinated by a cyanide anion and a water molecule in the axial sites, completing a distorted octahedral coordination geometry. In the crystal, pairs of bifurcated O-H(O,O) hydrogen bonds link adjacent molecules, forming centrosymmetric dimers. The acetonitrile solvent molecule shows 0.5 occupancy.
