摘要

Two new ternary copper complexes, [CuL1(H2O) (Pyz)] (1) [(LH2)-H-1 = 1(3,5-di-tert-butyl-2-hydroxybenzyl)amino } acetic acid] and [CuL2(H2O) (Pyz)] (2) [L-2 H-2 = 2-(3,5-di-tert-butyl-2-hydroxy-benzylamino)-3-methyl-butyric acid; Pyz = pyrazole] have been synthesized. The compounds have been characterized by various techniques including IR, LN-visible, circular dichroism (CD) (2) and EPR spectroscopy, electrochemical and magnetic susceptibility measurements. The crystal structure of 1 has been determined. The compound crystallizes in the space group P2(1)/a, with a = 10.6217(2) angstrom, b = 10.1645(2) angstrom, c = 19.4909(5) angstrom, 90.7729(9)degrees, V= 2104.13(8) angstrom(3) Z = 4. Cyclic voltammetry of the compounds show two reversible oxidative peaks due to metal centered and ligand centered oxidations. The compounds have been oxidized electrochemically and chemically and the oxidized species have been characterized by UV-visible and EPR spectroscopy. (c) 2007 Elsevier Ltd. All rights reserved.
