In the title coordination polymer, {[Ni(C19H17N4O2)2(H2O)2]·H2O}n, the Ni2+ cation is located on an inversion center and coordinated by two carboxylate O atoms from two different 3,5-bis(pyridin-4-ylmethylamino)benzoate anions, two O atoms from two coordinated water molecules and two N atoms from two different 3,5-bis(pyridin-4-ylmethylamino)benzoate anions, displaying a slightly distorted NiN2O4 octahedral geometry. Each 3,5-bis(pyridin-4-ylmethylamino)benzoate anion acts as a μ2-bridge, linking different nickel ions into a chain along [010]. In the crystal, adjacent chains are further linked through N—H...O, O—H...O, O—H...N and C—H...O hydrogen bonds into a three-dimensional network. The coordinated water molecules and a disordered water molecule of hydration with 0.50 site occupancy play an important role in the formation of these hydrogen-bonding interactions.
