Synthesis, Characterization, and Crystal Structure of a Novel Acetate‐bridged Polynuclear Schiff Base Copper(II) Complex

A novel acetate‐bridged polynuclear Schiff base copper(II) complex, [CuL(CH₃COO)]_n (L=4‐nitro‐2‐[(2‐methylaminoethylimino)methyl]phenol), has been synthesized and characterized by elemental analysis, IR spectrum and single crystal X‐ray diffraction. Each Cu atom in the complex is five‐coordinate in a trigonal‐bipyramidal configuration, with one imine N atom and two acetate O atoms defining the basal plane, and one phenolate O and one amine N atoms occupying the axial positions. The [4‐nitro‐2‐[(2‐methylaminoethylimino)methyl]phenolato]copper(II) units are linked by the bridging acetate ligands, forming polymeric chains running along the c axis.
