Bis[bis-(2,2'-bipyridine-κN,N')chloridocopper(II)] bis-(μ-2,6-pyridine-dicarboxyl-ato)-κO,N,O:O;κO:O,N,O-bis-[aqua-dichloridobismuthate(III)] penta-hydrate.

In the title compound, [CuCl(C(10)H(8)N(2))(2)](2)[Bi(2)Cl(4)(C(7)H(3)NO(4))(2)(H(2)O)(2)]·5H(2)O, the dianion [Bi(2)Cl(4)(C(7)H(3)NO(4))(2)(H(2)O)(2)](2-) is located about an inversion center. The Cu(II) atom of the cation is coordinated by four N atoms of the two chelating 2,2'-bypyridine ligands and one Cl(-) ion, completing a distorted trigonal-bipyramidal coordination environment. In the anion, each Bi(III) atom is seven-coordinate and is bonded to a tridentate pyridine-2,6-dicarboxyl-ate ligand, a water mol-ecule, two chloride ions and a bridging carboxyl-ate O atom of another carboxyl-ate ligand. The coordination geometry of Bi(III) is distorted penta-gonal-bipyramidal with the Cl(-) ions located in axial positions. The structure of the dianion is additionally stabilized by an intra-molecular O-H⋯O hydrogen bond between the coordinated water mol-ecule and carboxyl-ate O atom. In the crystal, O-H⋯O hydrogen bonds occur . The H atoms of the solvent water mol-ecules could not be located.
