Coordination compound chemistry is an important and challenging area of modern inorganic chemistry. New concepts of chemical bonding and molecular structure have shed light on how coordination compounds function as essential components of biological systems. Coordination compounds are used in a variety of metallurgical processes, industrial catalysts, and analytical reagents.
