In the centrosymmetric title complex, [Ni(2)(C(14)H(8)O(4)S(2))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], the Ni(II) atom is coordinated by two N atoms from one 2,2'-bipyridine ligand, three carboxyl-ate O atoms (one bidentate and one monodentate) from two different disulfanediyldibenzoate ligands and one O atom from a coordinated water mol-ecule in an octa-hedral coordination geometry. The disulfanediyldibenzo-ate dianion bridges two Ni(II )atoms. Adjacent mol-ecules are linked through the coordinated water mol-ecules, forming a O-H⋯O hydrogen-bonded chain running along the a axis.
