The asymmetric unit of the polymeric title complex, Cu(3)Na(2)(C(11)H(8)N(2)O(3))(4)(CH(4)O), consists of two Na(I) atoms, three Cu(II) atoms, four 5-(4-methoxy-phen-yl)pyrazole-3-carboxyl-ate ligands and one methanol mol-ecule. The central Cu(II) atom is coordinated by four N atoms from four pyrazole-3-carboxyl-ate ligands, forming a distorted tetra-hedral (CuN(4)) geometry, while each of the other two Cu(II) atoms is coordinated by two O atoms and two N atoms from the two ligands, forming a slightly distorted square-planar (CuN(2)O(2)) geometry. Each of the two Na(I) atoms is coordinated by five O atoms, forming a distorted octahedral geometry; four O atoms are from the carboxyl-ate groups of the three ligands and the remaining O atom is from the meth-oxy group of the ligand or from the methanol mol-ecule.
聚合物标题配合物Cu(3)Na(2)(C(11)H(8)N(2)O(3))(4)(CH(4)O)的不对称单元由两个Na(I)原子、三个Cu(II)原子、四个5-(4-甲氧基苯基)吡唑-3-羧酸酯配体和一个甲醇分子组成。中心Cu(II)原子由来自四个吡唑-3-羧酸酯配体的四个N原子配位，形成扭曲的四面体（CuN(4)）几何构型，而另外两个Cu(II)原子中的每一个都由来自两个配体的两个O原子和两个N原子配位，形成略微扭曲的平面正方形（CuN(2)O(2)）几何构型。两个Na(I)原子中的每一个都由五个O原子配位，形成扭曲的八面体几何构型；四个O原子来自三个配体的羧酸酯基团，其余的O原子来自配体的甲氧基或甲醇分子。
