SYNTHESIS AND CHARACTERIZATION OF SOME METAL COMPLEXES WITH IBA AS LIGAND DERIVED FROM 2–BENZOYLINDANE–1,3–DIONE
Journal Title: Journal of Biomedical and Pharmaceutical Research - Year 2014, Vol 3, Issue 1
Abstract
The present investigation are based on the synthesis and characterization of metal complexes with Schiff’s bases α– (1, 3– dioxo– indan– 2–yl) – benzylidene– aniline (IBA) derived from 2–Benzoylindane–1,3–Dione by condensing it with primary aryl amine (aniline) in absolute alcohol. 2–Benzoylindane–1,3–Dione was prepared by claisen-condensation. The Co (II), Ni(II), Cu (II), Zn (II), Cd (II), Fe (III), V (III) and Cr (III) complexes of the Schiff’s bases have been prepared in the reactions and investigated their structures by physicochemical methods. The formulation and structure of the ligands have been screened by their chemical analysis, IR, PMR and mass-spectral studies. The PMR spectrum of the metal complexes in quite similar to the PMR spectrum of the IBA with slight change in the position of PMR signals. The metal complexes are thermally stable at higher temperature. Results show that the complexes exhibit partial ionic character, though the complexes are covalent. The mass-spectra of this IETS showed the molecular ion peak as a base peak at m/z 261. The enolic formulation for the IBA got an additional support by a positive ferric chloride test. The structure of ligand has been confirmed by their mass– spectral studies.
