Poly[methano­ltetra­kis[μ(3)-5-(4-methoxy­phen­yl)pyrazole-3-carboxyl­ato(2−)]tri­copper(II)disodium(I)

The asymmetric unit of the polymeric title complex, [Cu(3)Na(2)(C(11)H(8)N(2)O(3))(4)(CH(4)O)](n), consists of two Na(I) atoms, three Cu(II) atoms, four 5-(4-methoxy­phen­yl)pyrazole-3-carboxyl­ate ligands and one methanol mol­ecule. The central Cu(II) atom is coordinated by four N atoms from four pyrazole-3-carboxyl­ate ligands, forming a distorted tetra­hedral (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 carboxyl­ate groups of the three ligands and the remaining O atom is from the meth­oxy group of the ligand or from the methanol mol­ecule.
