Tetrakis(μ-2-chloro-4-nitrobenzoato-κ²O:O′)bis[aquacopper(II)]

Abstract

In the title binuclear copper(II) complex, [Cu2(C7H3ClNO4)4(H2O)2], each of the two independent CuII 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—H⋯O, C—H⋯O and C—H⋯Cl hydrogen bonds. One of the Cl atoms is disordered over two positions with occupancies of 0.650 (2) and 0.350 (2).
