Abstract
1,5-bis(2-formylphenyl)pentane (synthesised from 1,5 dibromopentane and salicylaldehyde). reacts with 2,6-diaminopyridine to give a new macrocyclic ligand that gives Cu(II), Ni(II), Pb(II), Zn(II), Cd(II) and La(III) complexes by reaction with Cu(NO3)2·3H2O, Ni(NO3)2·6H2O, Pb(NO3)2, Zn(NO3)2·6H2O, Cd(NO3)2·4H2O and La(NO3)3·6H2O respectively. The ligand and its metal complexes have been characterised by elemental analysis, IR, 1H and 13C NMR, UV-Vis spectra, magnetic susceptibility, conductivity measurements and mass spectra. All complexes are diamagnetic and the Cu(II) complex is binuclear.
