The Co atom in the title complex, [Co(C7H8N4O)2](ClO4)2·H2O, is octahedrally coordinated by two molecules of the neutral Schiff bases derived from the condensation of pyridine-2-carb­aldehyde and semicarbazone; the Schiff base molecules act as meridional tridentate ligands, coordinating the metal through the amido O atom, imine N and pyridyl N atoms. The ligands are perpendicular to each other [dihedral angle = 87.27 (5)°]. The crystal packing is stabilized by intermolecular hydrogen bonds involving the cations, perchlorate counter-ions and water mol­ecules.
