Abstract: In the title binuclear copper(II) complex, [Cu₂(C₇H₃ClNO₄)₄(H₂O)₂], each of the two independent Cu^II center is five-coordinated by four O atoms of the carboxylate groups in the basal plane and one O atom of a water molecule in the apical position, in a distorted square-pyramidal geometry. The Cu-Cu distance is 2.6458 (4) Å. In the crystal structure, the dinuclear units are linked into a three-dimensional network by O-HO, C-HO and C-HCl hydrogen bonds. One of the Cl atoms is disordered over two positions with occupancies of 0.650 (2) and 0.350 (2).
