|Abstract:||Four copper(II) complexes containing the reduced Schiff base ligands, namely, N-(2-hydroxybenzyl)-glycinamide (Hsglym) and N-(2-hydroxybenzyl)-l-alaninamide (Hsalam) have been synthesized and characterized. The crystal structures of [Cu2(sglym)2Cl2] (1), [Cu2(salam)2(NO3)2] · H2O (3), [Cu2(salam)2(NO3)(H2O)](NO3) · 1.5H2O (4), [Cu2(salam)2](ClO4)2 · 2H2O (5) show that the Cu(II) atoms are bridged by two phenolato oxygen atoms in the dimers. The sglym ligand bonded to Cu(II) in facial manner while salam ligand prefers to bind to Cu(II) in meridonal geometry. Variable temperature magnetic studies of 3 showed it is antiferromagnetic. These Cu(II) complexes and [Cu2(sglym)2(NO3)2] (2), exhibit very small catecholase activity as compared to the corresponding complexes containing acid functional groups. © 2006 Elsevier B.V.
