Abstract
In the title compound, {[Cu2Na2(C10H2O8)1.5(H2O)6]·H2O}n, the Cu2+ ion is hexacoordinated by five O atoms from benzene-1,2,4,5-tetracarboxylate (btec4−) ligands and one water molecule. The Na+ ion is also hexacoordinated, by four O atoms from btec4− ligands and two water molecules. One of the two btec4− molecules sits on a crystallographic inversion centre. CuO6 and NaO6 octahedra are connected, forming bi-dimensional layers. These layers, which extend parallel to the ac plane, are further interconnected by μ10- or μ11-bridging btec4− ligands and by O—H⋯O hydrogen bonds, involving both btec4− ligands and water molecules, forming a three-dimensional network.
