In the molecule of the centrosymmetric title compound, [Co(C₂₅H₂₀N₂O₅)₂(H₂O)₄](ClO₄)₂·6H₂O, the Co atom is octahedrally coordinated by four water molecules lying in the equatorial plane and two monodentate carboxylate groups from two dicarboxylate ligands. The crystal structure involves O-HO and O-HCl hydrogen bonds..
