catena-Poly[[aqua­bis­[2-(3-benzoyl­phen­yl)propano­ato-κ(2) O (1),O (1′)]cadmium(II)]-μ-4,4′-bipyridine-κ(2) N: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 carboxyl­ate unit and exists in a seven-coordinate penta­gonal–bipyramidal geometry. The apical sites are occupied by N atoms. The water mol­ecule also lies on the twofold rotation axis. The methyl substituent of the propano­ate 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.
