摘要

In the title compound, [CuCl(C10H8N2)2]2[Bi2Cl4(C7H3NO4)2(H2O)2]·5H2O, the dianion [Bi2Cl4(C7H3NO4)2(H2O)2]2− is located about an inversion center. The CuII 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 BiIII atom is seven-coordinate and is bonded to a tridentate pyridine-2,6-dicarboxyl­ate ligand, a water mol­ecule, two chloride ions and a bridging carboxyl­ate O atom of another carboxyl­ate ligand. The coordination geometry of BiIII is distorted penta­gonal–bipyramidal with the Cl ions located in axial positions. The structure of the dianion is additionally stabilized by an intra­molecular O—H⋯O hydrogen bond between the coordinated water mol­ecule and carboxyl­ate O atom. In the crystal, O—H⋯O hydrogen bonds occur . The H atoms of the solvent water mol­ecules could not be located.
