The asymmetric unit of the title complex, [Ni-2(C16H6O8)(C10H8N2)(2)(H2O)(6)]center dot 6H(2)O, contains one Ni-II atom, one 2,2'-bipyridine ligand, three coordinated water molecules, one-half of a fully deprotonated biphenyl-3,3',4,4'-tetracarboxylate anion and three lattice water molecules. The Ni-II atom displays a distorted NiN2O4 octahedral coordination formed by one carboxylate O atom, three water O atoms and two N atoms of the chelating ligand. The complete biphenyl-3,3',4,4'-tetracarboxylate ligand displays inversion symmetry and links two symmetry-related Ni-II atoms into a binuclear complex. Neighbouring complex molecules are linked through O-H center dot center dot center dot O hydrogen bonds into a three-dimensional structure. Additional O-H center dot center dot center dot O hydrogen bonds between the lattice water molecules help to consolidate the crystal packing.
