Synthesis and characterization of complexes of a salicyladehyde Schiff base derivative with Mn(II), Co(II), Ni(II) and Pb(II)

Salman M.Saadeh

Anewseries ofmetal complexeswith a Schiff base ligand derived fromcondensation of 1,6-hexamethylene diamine and salicylaldehyde have been synthesized and characterized by elemental analysis, conductivity, thermogravimetric analysis, IR and electronic spectra. These complexes have the formulaML orML(CH3OH)2 where L is the Schiff base tetradentate ligand N,NÂ’-disalicylidenehexameythylenediamine (salhmnH2) that coordinates through N2O2. The studies reveal formation of square or octahedral complexes. These complexes are potentially useful in devising metal probes, catalysis, and as models for some metalloenzymes.c
