Abstract

Schiff bases are condensation product compounds obtained from the reaction of carbonyl group compounds with primary amines. The C=N bond formed due to the reaction is called the azomethine bond or imine bond. Coordination compounds formed by Schiff bases with metals have broad application areas and play essential roles as catalysts, biological agents, analytical reagents, materials, and environmental solutions. These compounds' various chemical and physical properties increase their importance in basic science research and industrial applications. These compounds' various chemical and physical properties increase their importance in basic science research and industrial applications. In this study, Schiff base ligands (3,5) were synthesized from the reaction of vanillin, an aldehyde compound, with primary amines in an acidic medium. The structure of the synthesized Schiff base ligands was characterized by 1H NMR, 13C NMR, and FTIR spectroscopy, and new metal complexes (6,7) were synthesized from the reaction with cadmium metal salt (Cd(NO3)2). The structures of the synthesized metal complex compounds were characterized by elemental analysis, FTIR, and thermogravimetric analysis, and their properties were investigated. Although the magnetic susceptibility of cadmium was investigated in the literature on metal complex studies, magnetic susceptibility analysis was not deemed necessary due to the low magnetic susceptibility of cadmium.
