| Abstract | ||
| The work the synthesis and characterisation of the new Ligand from Schiff base type (N2O2) with general formula[(C18H18N2O2)]. All compounds have been characterised as needed using spectroscopic methods, such as[FTIR,UV-Vis.], micro analysis of elements C.H.N, and molar conductivity measurements. The FT 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 the coordination 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 (Fe+2,Co+2,Ni+2andCu+2)) ions with the ligand is square planner or tetrahedral. The supported studies by magnetic measurements the value of magnetic moments of Fe(II), Co(II), Ni(II), and Cu(II) complexes shows that they are paramagnetic, other complexes show diamagnetic properties. The stoichemetry of formed complexes were studies using the mole ratio method which showed that the ratio (M:L) is (1:1) for the all ion complexes. The degree of dissociation (α) and the stability constant (Ksta.) of the complexes were calculated. The conductivity measurements showed that, All complexes are electrolyte with (1:2). | ||
