摘要：

New N-functionalized tetraaza macrocyclic ligand [N-{(2-hydroxy-3-formyl-5-bromo)benzyl}-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane (L)] and its nickel(II) complex has been prepared and characterized. The X-ray structural analysis of [NiL](ClO4) . H2O showed that the geometry around nickel(II) ion is distorted trigonal bipyramid. Cyclic voltammetric studies of Ni(II) complex show one electron irreversible reduction at E-pc = -1.49 V and oxidation at E-pa = 1.12 V. Nickel(II) complex has a room temperature magnetic moment value of mu(eff) = 3.35 B.M. (C) 2005 Elsevier B.V. All rights reserved.
