Aqua-(2,2'-bipyridine-κN,N')bis-(4-iodo-benzoato-κO)copper(II).

The Cu(II) atom in the title compound, [Cu(C(7)H(4)IO(2))(2)(C(10)H(8)N(2))(H(2)O)], is N,N'-chelated by a 2,2'-bipyridine ligand and is coordinated by two monodentate carboxyl-ate ions and a water mol-ecule in a distorted square-pyramidal geometry. The apical site is occupied by one of the carboxyl-ate O atoms. The water mol-ecule forms intra-molecular hydrogen bonds to the uncoordinated carboxyl O atoms. The crystal studied was a nonmerohedral twin with minor components in 0.381 (3) and 0.108 (2) proportions.
