Synthesis And Characterization Of The Schiff Based Ligands And Complexes

The schiff based ligands and the corresponding complexes of schiff bases are rather important for their various structures and extensive applying in the field of catalysis, bioactivity, and material etc. Therefore, we designed and synthesized some new schiff based ligands and their complexes of transition metals in this paper.The main work is described as follows:1.A schiff based ligand of (4-Bromobenzylidene) has been designed and synthesized.2.A ligand based on l-phenyl-3-methyl-4-benzoyl-5-pyrazolone and the corresponding complexes with transition metal of Fe(II), Cu(II), Co(II) have been designed and synthesized.3. These ligands and complexes are characterized by IR spectrum, Elemental analysis and X-ray single crystal diffraction. The single molecular analysis are given.4.The single crystal structures of four ligand (C₁₅H₁₄BrN, C_{13H10BrNO, C18H12N3O, C25H23N3O, C18H12N3O} and three corresponding complexes (Fe(C₂₇H₂₀N₃O)₂ , Cu(C₂₄H₂₀N₃O)₂ , Co(C₂₄H₂₀N₂O)₂ ) are obtained. The molecular structures and the space anarthrias are discussed.
