Abstract: The title compound, [Cu(C₁₂H₁₆N₃O₃)(CH₃COO)]_n or [Cu(CMP)(CH₃COO)]_n {CMP is 2-[3-(dimethylamino)propyliminomethyl]-4-nitrophenol}, was synthesized by the reaction of 2-hydroxy-5-nitrobenzaldehyde, N,N-dimethylpropane-1,3-diamine and copper(II) acetate monohydrate in a methanol solution. The compound is an acetate-bridged polymeric copper(II) complex. The Cu^II atom is coordinated in a square-pyramidal manner by one Schiff base CMP ligand and two acetate anions. The Schiff base molecule acts as a tridentate ligand, coordinating the Cu^II ion through its phenolate O atom, imine N atom and amine N atom. The acetate anion acts as a bridging group, coordinating two adjacent Cu^II ions through its two O atoms, one in the basal plane and the other in the apical position. The [Cu(CMP)] units are linked through the bridging acetate groups, forming chains running along the c axis.
