Schiff bases, due to their ease of synthesis, structural versatility, and strong metal-binding properties, have gained
attention in coordination chemistry, catalysis, and medicinal applications. This study presents the synthesis of
Schiff base ligands through condensation reactions of aromatic aldehydes with primary amines and investigates
their coordination behavior with transition metal ions such as Cu(II), Ni(II), and Co(II). The resulting ligands
and their metal complexes were characterized using Fourier-transform infrared spectroscopy (FTIR), ultravioletvisible
(UV-Vis) spectroscopy, nuclear magnetic resonance (NMR), elemental analysis, and molar conductivity
measurements. The spectroscopic results revealed successful metal-ligand coordination, confirmed by significant
shifts in key functional group bands and electronic transitions. The study demonstrates the effectiveness of Schiff
base ligands as potent chelators and provides comparative insights into their coordination modes with different
metal ions
