Abstract

New Schiff base derivatives (L-1 and L-2) were prepared by the condensation of 2-hydroxy-3-methoxybenzaldehyde (o-vanillin) and 3-hydroxy-4-methoxybenzaldehyde (iso-vanillin) with 5-methylfurfurylamine. Two new complexes [Ni(L-1)(2)] and [Cu(L-1)(2)] have been synthesized with bidentate NO donor Schiff base ligand (L-1). The Ni(II) and Cu(II) atoms in each complex are four coordinated in a square planar geometry. Schiff bases (L-1 and L-2) and complexes [Ni(L-1)(2)] and (Cu(L-1)(2)] were characterized by elemental analyses, FT-IR, UV-vis, mass and H-1, C-13 NMR spectroscopies. The crystal structures of the ligand (L-2) and complexes [Ni(L-1)(2)] and [Cu(L-1)(2)] have also been determined by using X-ray crystallographic technique. (C) 2011 Elsevier B.V. All rights reserved.
