A pent dentate ligand H2L was prepared by condensation reaction of one mole 2,6-diacetyl pyridine and two moles of 1,2-phenylene diamine, followed condensation with ethanol solution of salicyaldehyde The newl poly dentate (H2L) was identified on the basis of CHN micro elemental analysis, H and 13C NMR spectra. The manganese(II), cobalt (II), nickel(II), copper(II) and cadmium(II) have been isolated in the solid states and fully characterized on the basis of CHNM elemental analyses, FTIR, UV-Visible spectra, molar conductivity measurements and the magnetic moments. All the complexes have been assigned as octahedral geometry of general formula [ML] where M = Mn(II), Co(II), Ni(II), Cu(II) and Cd(II).
Macro cyclic ligand, polydentate ligands type N4O2 system
