<![CDATA[A new ligands (H2L1, H2L2) and Theirs Binuclear complexes with (SmIII ,CeIII, NiII and CuII ). Both ligands prepare in two steps, the first step dissolution of terephthaldehyde in methanol and reacted under refluxe with O- phenylen diamine to give N1,N1,-(1,4-Phenylenebis (methanylylidene) bis(benzene-1,2-diamine) which reacted in the second step with O-Vanillin to give the ligand6,6,-((1E,1,E)-((((1,4-Phenylenebis (methanylylidene)) bis(azanylylidene)) bis(2,1- phenylene) ) bis(azanylylidene bis(methanylylidene) bis(2- meth oxyphenol) (H2L1) and reacted with 2-Hydroxy-1- naphthaldehyde to give the ligand 1,1,-((1E)-((((1,4-phenylenebis (methanylylidene)) bis(azanylylidene)) bis (2,1- phenylene)) bis(azanylylidene))bis(methanylylidene)bis(naphthalene-2-ol (H2L2 ).The four complexes manufacture by immediate reaction of the ligands with appropriate metal chloride. The ligands and Theirs complexes were characterize by spectroscopic methods ,Elemental Analysis (C.H.N),Infrared Spectroscopy (FT-I.R), Nuclear Magnetic Resonance Spectroscopy (1H-NMR), Mass Spectra , Magnetic sensitivity and Molar conductivity . The data of these measurements suggest a Sequare planer geometry for (CuII , NiII) , Monocapped octahedron for Ce III and Sm III complexes .Keywords: Binuclear complexes, Terephthaldehyde, Schiff base, Inner-transition metals.]]>
