Poly[tetraaqua(μ6-benzene-1,2,4,5-tetracarboxylato)dicopper(II)

Abstract

The title compound, [Cu2(C10H2O8)(H2O)4]n, is isostructural with the analogous Zn polymeric compound [Wang, Lu, Yang, Zhao & Ng (2007). Acta Cryst. E63, m2986]. Each CuII ion is coordinated by five O atoms [Cu—O = 1.968 (2)–2.268 (3) Å] in a trigonal–bipyramidal geometry. The coordinating water mol­ecules are involved in inter­molecular O—H⋯O hydrogen bonds [O⋯O = 2.726 (3)–2.767 (3) Å], which consolidate the packing.
