Abstract: In the title complex, {[Ni2(C14H4N2O8)(H2O)6]·2H2O}n, the two NiII atoms are located in different special positions (one on a twofold rotation axis and the second on a centre of symmetry) and have different distorted octahedral environments (one by two N atoms from a bipyridine unit, two O atoms from two water molecules and two O atoms from two carboxylate groups, and the second by four O atoms from four water molecules and two O atoms from two carboxylate groups). Thus, the environments of the NiII atoms may be denoted as NiN2O4 and NiO6. In the crystal, there exists an extensive network of classical O-H...O hydrogen bonds.
