Poly[[aqua-(μ(2)-4,4'-bipyridine-κ(2)N:N')[μ(3)-3-bromo-2-(carboxyl-atometh-yl)-benzoato-κ(3)O(1):O(1'):O(2)]cadmium] monohydrate].
In the title compound, {[Cd(C(9)H(5)BrO(4))(C(10)H(8)N(2))(H(2)O)]·H(2)O}(n), the Cd(II) atom has a distorted octa-hedral coordination geometry. Two N atoms from two 4,4'-bipyridine (bipy) ligands occupy the axial positions, while the equatorial positions are furnished by three carboxyl-ate O atoms from three 3-bromo-2-(carboxyl-atometh-yl)benzoate (bcb) ligands and one O atom from a water mol-ecule. The bipy and bcb ligands link the Cd(II) atoms into a three-dimensional network. O-H⋯O hydrogen bonds and π-π inter-actions between the pyridine and benzene rings [centroid-centroid distance = 3.736 (4) Å] are present in the crystal.
