Poly[methano­ltetra­kis[μ3-5-(4-methoxy­phen­yl)pyrazole-3-carboxyl­ato(2−)]tri­copper(II)disodium(I)

The asymmetric unit of the polymeric title complex, [Cu3Na2(C11H8N2O3)4(CH4O)]n, consists of two NaI atoms, three CuII atoms, four 5-(4-methoxy­phen­yl)pyrazole-3-carboxyl­ate ligands and one methanol mol­ecule. The central CuII atom is coordinated by four N atoms from four pyrazole-3-carboxyl­ate ligands, forming a distorted tetra­hedral (CuN4) geometry, while each of the other two CuII atoms is coordinated by two O atoms and two N atoms from the two ligands, forming a slightly distorted square-planar (CuN2O2) geometry. Each of the two NaI 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.
