Synthesis and characterization of some new coordination compounds and their metal oxides to be used in variable applications

Abstract

Eight new Schiff base complexes are prepared from the reaction of Ag(I), Cr(III), Fe(III), Co(II), Cu(II), Cd(II), Hg(II) and U(VI) metal ions with Schiff base ligand, N1,N2-bis(furan-2-ylmethylene)-4-methylbenzene-1,2-diamine (L). Also, Fe(III), Co(II), Cu(II) and Cd(II) mixed ligand complexes are synthesized in the presence of 2,2`-bipyridine as a second ligand. The ligand and its complexes are characterized by elemental analysis, spectroscopic studies such as mass spectra, molar conductance, IR, 1H NMR, solid reflectance, magnetic susceptibility measurements, thermal analysis and PXRD study. Mass spectrum of the ligand agreed with the proposed molecular formula, C17H14N2O2, and presence of its molecular ion peak in the mass spectra of the complexes confirming the complexation. Conductance data shows that the complexes are electrolytes except Co(II), Cu(II), and Hg(II) metal complexes are shown to be non-electrolytes.
