COMPLEX COMPOUNDS: STRUCTURE, PROPERTIES, AND MEDICAL SIGNIFICANCE

This article reviews the chemistry and medical applications of complex compounds. Complexes consist of a central atom or ion surrounded by ligands, forming coordination bonds that determine their structure and properties. Their unique chemical and physical characteristics enable applications in pharmaceutical drugs, diagnostics, and the regulation of biological processes. Platinum, copper, zinc, and gadolinium complexes are highlighted for their therapeutic and imaging uses. Challenges such as toxicity, stability, and synthesis complexity are discussed, along with future prospects involving targeted therapy, nanotechnology, and personalized medicine. Complex compounds remain critical in advancing modern medical research and clinical practice.
