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)center dot 3H(2)O, Ni(NO3)(2)center dot 6H(2)O, Pb(NO3)(2), Zn(NO3)(2)center dot 6H(2)O, Cd(NO3)(2)center dot 4H(2)O and La(NO3)(3)center dot 6H(2)O respectively. The ligand and its metal complexes have been characterised by elemental analysis, IR, H-1 and C-13 NMR, UV-Vis spectra, magnetic susceptibility, conductivity measurements and mass spectra. All complexes are diamagnetic and the Cu(II) complex is binuclear.
