Triazole containing compounds are very important due to their vast utility in medicinal, pharmaceutical, industrial, catalytic and agro-medicinal field. The Schiff base ligands incorporating triazole moiety and their derived metal complexes are of great interest due to their bonding beauties, structural diversities and easiness to prepare. The wide range of biological activities has created huge research interest in these compounds.
Triazole derived Schiff base ligand, 5-methyl-4-[(E)-(phenylmethylidene) amino]-4H-1,2,4-triazole-3-thiol (HL) and its metal complex with Cd(II) and Hg(II) was prepared in solid state. Green solvent free method was also applied for synthesis of ligand. The prepared compounds were characterized by elemental analysis, Infrared spectroscopy, NMR spectroscopy, magnetic moment & electrical conductivity data and Scanning electron microscopy analysis.
The ligand (HL) is potentially N,S donor molecule. The elemental analysis suggest that complexes have composition [M(L)2] where M= Metal and L=Deprotonated ligand. The electrical conductivity values suggests that compounds are non-electrolytes. The metal complexes are diamagnetic in nature. The proton NMR spectra of ligand and its Hg(II) complex in DMSO-D6 indicated that ligand exists in thiol form and deprotonation of ligand is observed in Hg(II) complex. The infrared spectra of complexes clearly indicate that ligand is bidentate, donating to metal through aldimine N-atom and deprotonated thiol group. The SEM analysis was utilized to study the morphology and topography of the prepared compounds.
The schiff base ligand (HL) and its metal complexes with Cd(II) and Hg(II) ions were prepared and characterized using elemental and various spectral techniques. SEM analysis was used to describe the morphology of compounds. The complexes are neutral with composition [M(L)2]. The NMR and IR spectra confirmed the formation of ligand and revealed that ligand is bidentate chelating molecule donating from aldimine N-atom and thiol group S-atom.
