Synthesis and Spectroscopic Study of Azo-Schiff Base Compound and Its Complexes with Cobalt and Nickel

Azo compounds are known for their diverse applications in coordination chemistry, yet their potential with specific ligands remains underexplored. This study aimed to synthesize and characterize a new azo compound through a two-step reaction involving 4-nitroaniline and 2-hydroxynaphthaldehyde, followed by condensation with 4,4-diaminodiphenylmethane. The resulting ligand was then complexed with cobalt and nickel. The ligand and its metal complexes were characterized using elemental analysis, FT-IR, mass spectrometry, and 1H NMR. The findings provide insights into the structural properties of the ligand and its complexes, contributing to the understanding of their potential in catalysis, materials science, or pharmaceutical applications.
