Coordination chemistry is a sub-discipline of inorganic chemistry that focuses on the study of coordination compounds, which are complexes composed of a central metal atom or ion bonded to surrounding ligands. Coordination compounds are widely used in various fields, including materials science, catalysis, medicinal chemistry, and bioinorganic chemistry. In coordination chemistry, researchers study the structure, bonding, and properties of coordination compounds, as well as their applications in different areas. This field also explores the synthesis and characterization of coordination compounds, as well as the mechanisms of their reactions and transformations. Overall, coordination chemistry plays a crucial role in advancing our understanding of the behavior of metal complexes and their interactions with other molecules, which has important implications for various fields of chemistry and beyond.
