Abstract: Schiff base transition metal complexes have emerged as a pivotal class of compounds in coordination chemistry due to their structural diversity, facile synthesis, and broad-spectrum biological activities. This review critically compiles and analyzes literature from 2000 to 2013, emphasizing synthetic methodologies, coordination behavior, and characterization techniques of Schiff base ligands and their complexes with transition metals. Particular attention is given to their promising applications in antimicrobial, antioxidant, anticancer, and catalytic domains. The role of the azomethine (-C=N-) functional group in ligand-metal binding and its impact on physicochemical properties is discussed in detail. Advances in understanding structure-activity relationships highlight how metal ion identity and ligand substituents influence bioactivity and selectivity. Challenges such as limited substrate scope and stability issues are also addressed, alongside prospects for future research involving novel Schiff base frameworks and sustainable synthesis routes. This comprehensive overview serves as an essential resource for scientists exploring Schiff base complexes in bioinorganic and medicinal chemistry.
