Poly[[aqua­(μ(2)-4,4′-bipyridine-κ(2) N:N′)[μ(3)-3-bromo-2-(carboxyl­atometh­yl)­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 octa­hedral coordination geometry. Two N atoms from two 4,4′-bipyridine (bipy) ligands occupy the axial positions, while the equatorial positions are furnished by three carboxyl­ate O atoms from three 3-bromo-2-(carboxyl­atometh­yl)benzoate (bcb) ligands and one O atom from a water mol­ecule. The bipy and bcb ligands link the Cd(II) atoms into a three-dimensional network. O—H⋯O hydrogen bonds and π–π inter­actions between the pyridine and benzene rings [centroid–centroid distance = 3.736 (4) Å] are present in the crystal.
