The work included the synthesis and characterisation of the new Ligand from secondary ammines type (N2O2) with general formula[(C19H24N2O2)].Also the work covers the reaction of some metal ions with ligands complexes have general formula: [M (L)]Cl2 , M =[Fe+2, Co+2, Ni+2and Cu+2].All compounds have been characterised as needed by spectroscopic methods [FTIR,UV–Vis.], elemental analysis (C.H.N), m.p and molar conductivity measurements.The IR spectra of prepared complexes showed some charges in the band shape and density compared with those of the free ligand, new bands have been also observed which may indicate that thecoordination between the metal ions and ligand are exist.The C.H.N result shows the corresponding between the actual and calculated values.From the above data the proposed geometry around Cu+2 is square planner while (Fe+2,Co+2,Ni+2) ions with the ligand is tetrahedral.The supported studies by magnetic measurements the value of magnetic moments of Cu(II) complex shows diamagnetic properties, other complexes Fe(II), Co(II), Ni(II), show paramagnetic properties.The conductivity measurements showed that, All complexes are electrolyte with (1:2).
