Di-μ-chlorido-bis­[(2′-carb­oxybiphen­yl-2-carboxyl­ato-κO)(2,2′:6′,2′′-terpyridine-κ(3) N,N′,N′′)cadmium(II)] hemihydrate

In the centrosymmetric dinuclear title compound, [Cd(2)(C(14)H(9)O(4))(2)Cl(2)(C(15)H(11)N(3))(2)]·0.5H(2)O, each of the Cd(II) ions is coordinated by three N atoms from a chelating 2,2′:6′,2′′-terpyridine ligand, two bridging Cl atoms and one O atom of a 2′-carb­oxy-[1,1′-biphen­yl]-2-carboxyl­ate anion. The coordination environment is distorted octa­hedral. In the crystal, inter­molecular O—H⋯O hydrogen bonds link symmetry-related mol­ecules, forming an infinite chain. The half-occupancy water mol­ecule is disordered over two general sites with 0.25 occupancy and is, in turn, disordered over an inversion center.
