Synthesis and Characterization of Novel Mn(II), Fe(II) and Fe(III) complex of 5-ethyl-4-[(E)- (phenylmethylidene) amino]-4H-1,2,4-triazole-3-thiol

Abstract

Abstract: The synthesis and characterization of metal complexes with Triazole Schiff Base ligand is of great utility as these compounds possesses a wide variety of biological and medicinal properties. 1,2,4-triazole Schiff base ligand, 5-ethyl-4-[(E)- (phenylmethylidene) amino]-4H-1,2,4-triazole-3-thiol and its metal complexes with Mn(II), Fe(II) and Fe(III) were prepared. The ligand was characterized by micro analytical technique and FT-IR, 1H & 13C NMR spectroscopy. The IR spectra of the metal complex revealed that ligand is bidentate and donating to metal ion from deprotonated thiol group (S- ) and azomethine Natom. On the basis of elemental analysis data, octahedral geometry was proposed for the prepared metal complexes. Lattice water is also associated with all the prepared metal complexes.
