catena-Poly[[aqua-bis-[2-(3-benzoyl-phen-yl)propano-ato-κO,O]cadmium(II)]-μ-4,4'-bipyridine-κN:N'].

The 4,4'-bipyridine heterocycle in the polymeric title compound, [Cd(C(16)H(13)O(3))(2)(C(10)H(8)N(2))(H(2)O)](n), links adjacent Cd(II) ions into a chain running along the c axis. The Cd atom, which lies on a twofold rotation axis, is chelated by the carboxyl-ate unit and exists in a seven-coordinate penta-gonal-bipyramidal geometry. The apical sites are occupied by N atoms. The water mol-ecule also lies on the twofold rotation axis. The methyl substituent of the propano-ate group is disordered over two positions in a 1:1 ratio. O-H⋯O hydrogen bonding between water molecules and adjacent carboxylate O atoms is observed.
