Coordination compounds

Coordination compounds are chemical structures formed when central metal atoms bond with surrounding molecules or ions, known as ligands. These ligands can be neutral molecules or charged ions that interact with the metal, creating a complex. This arrangement imparts unique properties, such as color and reactivity, making them significant in various fields, including chemistry, biology, and materials science. Common examples include hemoglobin in blood and various catalysts in industrial processes. Coordination compounds play a crucial role in essential biological functions and are widely used in medicine, agriculture, and technology.
