Synthesis, spectroscopic, characterization and different applications of some schiff base transition metal complexes

Abstract

Thermal reaction of Cr(III), Co(II), Ni(II), Cu(II), Ag(I), Sm(III) and UO22+ metal ions with the synthesized Schiff base ligand 8-((furan-2-ylmethylene)amino)naphthalene-1-amine, L, resulted in the formation of the seven complexes: [CrLCl(H2O)3]Cl2.3H2O, [CoL2(H2O)2]Cl2.3H2O, [NiL(H2O)2]Cl2.4H2O, [CuL(H2O)2]Cl2.2H2O, [AgL(H2O)2]NO3.2H2O, [SmL3](ClO4)3(H2O), and [U(O)2L2](ClO4)2. The studied compounds are characterized using different spectroscopic techniques (IR, 1H NMR, mass), elemental analyses, magnetic measurement, molar conductance, and thermal analysis. Tetrahedral structures have been proposed for Ni(II), Cu(II) and Ag(I) complexes, whereas the other complexes are
