title: Poly[[hexa-aqua-sesqui(μ-benzene-1,2,4,5-tetra-carboxyl-ato)dicopper(II)disodium] monohydrate].
abstract: In the title compound, {[Cu2Na2(C10H2O8)1.5(H2O)6]·H2O} n , the Cu(2+) ion is hexa-coordinated by five O atoms from benzene-1,2,4,5-tetra-carboxyl-ate (btec(4-)) ligands and one water mol-ecule. The Na(+) ion is also hexa-coordinated, by four O atoms from btec(4-) ligands and two water mol-ecules. One of the two btec(4-) mol-ecules sits on a crystallographic inversion centre. CuO6 and NaO6 octa-hedra are connected, forming bi-dimensional layers. These layers, which extend parallel to the ac plane, are further inter-connected by μ10- or μ11-bridging btec(4-) ligands and by O-H⋯O hydrogen bonds, involving both btec(4-) ligands and water mol-ecules, forming a three-dimensional network.
