title: Bis(μ-biphenyl-2,2'-dicarboxyl-ato)bis-[aqua-(2,2'-bipyridine)cadmium(II)].
abstract: In the centrosymmetric dinuclear mol-ecule of the title compound, [Cd(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], the Cd(2+) ion is coordinated by three O atoms from two different diphenyl-dicarboxyl-ate (dpa) ligands (one O,O'-bidentate and one monodentate), a chelating bipyridine ligand and a water mol-ecule, generating an extremely distorted trigonal-prismatic (or irregular) CdN(2)O(4) coordination geometry for the metal ion. The bridging ligands generate an 18-membered ring, which is stabilized by two pairs of intra-molecular O-H⋯O hydrogen bonds.
