Synthesis and characterization of some transition metal complexes with new mixed-donor schiff base ligands derived from 2-hydroxynaphthaldehyde

Abstract

2-[3-(2-Formylnaphthoxy)-2-hydroxypropoxy] naphthaldehyde (1) have been prepared by reaction of 2-hydroxynaphthaldehyde with 1,3-dichloro-2-propanol. New N2O3 macro-acyclic ligands (L1, L2) synthesized from the reaction of (1) with aniline or cyclohexylamine. Ni (II), Co (II) and Cu (II) complexes was prepared from reaction of Schiff-bases with metal chloride and nitrate salts. All of these compounds characterized by FT-IR, 1H and 13C NMR, mass spectroscopy, elemental analysis, DSC and TGA techniques. Electrochemical behaviors, spectroscopic measurements and conductivity studies of the complexes were reported.
