A novel copper(II) complex of mixed ligands 2-acetylpyridine and N-ethylene(2-acetylpyridineimine) has been prepared by condensation and its crystal structure determined by XRD. The central copper(II) atom of the complex anion is coordinated to one oxygen of 2-acetylpyridine and four nitrogen atoms of the Schiff base in a distorted square pyramidal geometry. It has a similar coordination geometry to that found in Cu/Zn-SOD.
