Tetra-kis(μ-2-iodo-benzoato-κ ² O:O′)bis- [aquacopper(II)]

In the centrosymmetric binuclear title complex, [Cu ₂(C ₇H ₄IO ₂) ₄(H ₂O) ₂], the two Cu ^II ions [Cu⋯Cu = 2.6009 (5) Å] are bridged by four 2-iodo-benzoate (IB) ligands. The four nearest O atoms around each Cu ^II ion form a distorted square-planar arrangement, the distorted square-pyramidal coordination being completed by the O atom of the water mol-ecule at a distance of 2.1525 (16) Å. The dihedral angle between the benzene ring and the carboxyl-ate group is 25.67 (13)° in one of the independent IB ligands and 6.44 (11)° in the other. The benzene rings of the two independent IB ligands are oriented at a dihedral angle of 86.61 (7)°. In the crystal, O-H⋯O inter-actions link the mol-ecules into a two-dimensional network. π-π contacts between the benzene rings [centroid-centroid distances = 3.810 (2) and 3.838 (2) Å] may further stabilize the structure.
