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 bidimensional layers. These layers, which extend parallel to the ac plane, are further interconnected by 10- or 11-bridging btec4 ligands and by O--H O hydrogen bonds, involving both btec4 ligands and water molecules, forming a threedimensional network.
