Abstract

Bis-bidentate Schiff base ligand L and its two mononuclear complexes [CuL(CH3CN)2]ClO4(1) and [CuL(PPh3)2]ClO4(2) have been prepared and thoroughly characterized by elemental analyses, IR, UV-Vis, NMR spectroscopy and X-ray diffraction analysis. In both the complexes the metal ion auxiliaries adopt tetrahedral coordination environment. Their reactivity, electrochemical and photophysical behavior have been studied. Complex 1 shows reversible CuII/Icouple with potential 0.74 V versus Ag/AgCl in CH2Cl2. At room temperature L is weakly fluorescent in CH2Cl2, however in Cu(I) complexes 1 and 2 the emission in quenched. © 2009 Elsevier B.V. All rights reserved.
