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.
在标题化合物{[Cu₂Na₂(C₁₀H₂O₈)₁.₅(H₂O)₆]·H₂O}ₙ中，Cu(Ⅱ)离子由来自苯-1,2,4,5-四羧酸根（btec(4-)）配体的五个O原子和一个水分子六配位。Na(Ⅰ)离子也由来自btec(4-)配体的四个O原子和两个水分子六配位。两个btec(4-)分子中的一个位于晶体学反演中心上。CuO₆和NaO₆八面体相连，形成二维层。这些平行于ac平面延伸的层通过μ₁₀或μ₁₁桥连的btec(4-)配体以及O—H⋯O氢键进一步相互连接，涉及btec(4-)配体和水分子，形成三维网络。
