Abstract: In the title compound, {[Cd(C₉H₅BrO₄)(C₁₀H₈N₂)(H₂O)]·H₂O}_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-HO hydrogen bonds and [pi] - [pi] interactions between the pyridine and benzene rings [centroid-centroid distance = 3.736 (4) Å] are present in the crystal.
