Bis(μ-2,2′-disulfanediyldibenzoato)bis­[aqua­(2,2′-bipyridine)­nickel(II)]

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 carboxyl­ate O atoms (one bidentate and one monodentate) from two different disulfanediyldibenzoate ligands and one O atom from a coordinated water mol­ecule in an octa­hedral coordination geometry. The disulfanediyldibenzo­ate dianion bridges two Ni(II )atoms. Adjacent mol­ecules are linked through the coordinated water mol­ecules, forming a O—H⋯O hydrogen-bonded chain running along the a axis.
