Abstract: The Co atom in the title complex, [Co(H-Pysc)₂(H₂O)₄](CH₃COO)₂ {where H-Pysc is 3-[2-(aminocarbonyl)hydrazonomethyl]pyridine, C₁₄H₁₆N₈O₂}, occupies an inversion centre and is octahedrally coordinated by four aqua ligands and two molecules of the neutral Schiff base derived from the condensation of pyridine-3-carbaldehyde and semicarbazone (H-Pysc); the Schiff base molecules act as monodentate ligands, coordinating the metal through the pyridyl N, with the amide O and imine N atoms remaining uncoordinated. The crystal packing is stabilized by intermolecular hydrogen bonds involving the cations and acetate counter-ions.
