Abstract: The asymmetric unit of the polymeric title complex, [Cu₃Na₂(C₁₁H₈N₂O₃)₄(CH₄O)]_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 (CuN₄) 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 (CuN₂O₂) 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.
