In the title compound, (C6H10N2)[Co(C7H3NO4)2]·5H2O, the CoII ion is six-coordinated in an N2O4 environment by two pyridine-2,6-dicarboxylate (pydc) ligands, having a distorted octahedral geometry. The crystal packing is stabilized by intermolecular N—H...O, O—H...O and weak C—H...O hydrogen bonds. There are also π–π interactions between the pyridine rings of the pydc ligands and between the pydc ligands and the benzene-1,3-diammonium cations, with centroid–centroid distances of 3.4575 (15) and 3.7521 (15) Å.
