Cu(II) complexes of sterically and electronically divergent β-diketiminate ligands: Structural and electrochemical aspects

Cu(II) complexes of beta-diketiminate ligands with divergent N-aryl substitutions are reported. Exclusive formation of mononuclear [LCu(OAc)] complexes in the case of -CN substituted ligands and hydroxy bridged dinuclear [LCu(OH)](2) complexes in the case of -NO2 substituted ligands is observed. Most of the complexes were characterized by single crystal X-ray diffraction studies. Cyclic-voltammetric studies carried out on these complexes show that the reduction potentials correlate well with the expected electronic effects. (C) 2014 Elsevier Ltd. All rights reserved.
