The transition metals combine to form a large number of complex compounds in which metal atoms are bound to a number of anions or neutral molecules via electron sharing. Such compounds are known as coordination compounds in modern parlance. Coordination compound chemistry is an important and challenging area of modern inorganic chemistry.
