Two new unsaturated 12-membered tetraazamacrocyclic Schiff bases, 2,3:8,9-bis(4,5-dimethylbenzo)-5,6,11,12-tetraphenyl-1,4,7,10-tetrazazacyclododeco-1,4,6,10-tetraene (L 1) and 2,3:8,9-bis(4,5-dimethylbenzo)-5,6,11,12-tetramethyl-1,4,7,10-tetrazazacyclododeco-1,4,6,10-tetraene (L 2), and their copper(Ⅱ) complexes, [CuLX 2] (L=L 1 or L 2,X=Cl - or NO - 3), have been synthesized and characterized by means of elemental analyses, molar conductance, magnetic moments, IR, electronic and ESR spectra. It has been concluded that the metal ion is in an elongated octahedral environment with four equatorial nitrogen donors from the tetraazamacrocyclic ligands and two axial donors from the anions.
