In the title compound, *H2O, the Co^III ion is surrounded by three thiolate S atoms and three azomethine N atoms which define a fac-octahedral geometry that is highly distorted owing to the presence of three four-membered N,S-chelate rings.All three bidentate ligands are planar to within +/-0.06 Angstroem and display bond lengths and angles very close to expected values.Intermolecular hydrogen bonding between the water O atom and an uncoordinated pyrimidine N atom stabilizes the molecular packing.
