COORDINATION COMPLEX Meaning and
Definition
-
A coordination complex is a compound composed of a central metal ion or atom, surrounded by a group of ligands, that are typically molecules or ions that can donate a pair of electrons to the central metal. These ligands form coordinate covalent bonds with the metal, meaning the metal ion donates an electron pair to the ligand to form the bond.
The coordination complex consists of the central metal, ligands, and any associated counterions or neutral molecules. The central metal can be transition metals like iron, copper, or cobalt, or even nonmetals like tin or silicon. The ligands can vary greatly in nature and can include molecules such as ammonia, water, or carbon monoxide, as well as ions such as chloride or cyanide.
The coordination complex forms a three-dimensional structure around the central metal, known as the coordination sphere. This sphere is stabilized by attractive electrostatic interactions between the metal ion and the ligands. The coordination complex can have multiple ligands surrounding the central metal, and their arrangement can greatly affect the properties and reactivity of the complex.
Coordination complexes are widely studied in the field of inorganic chemistry due to their significant role in various biological, industrial, and catalytic processes. Their unique structures and properties make them useful in many applications, such as catalysis, drug design, and materials science. Understanding the formation, structure, and reactivity of coordination complexes is crucial in advancing our knowledge and applications in the field of chemistry.

Etymology of COORDINATION COMPLEX
The word "coordination" in coordination complex is derived from the Latin word "coordinatio", which means "orderly arrangement".
The term "coordination complex" was coined by the German chemist Alfred Werner in the late 19th and early 20th century. Werner's groundbreaking work in coordination chemistry involved studying the structures and bonding of metal ions with other molecules or ions, known as ligands, to form complex compounds.
The word "complex" in coordination complex is used to describe the structure that arises from the coordination of a central metal ion with multiple ligands. In essence, it refers to the complex arrangement and bonding between the metal ion and the ligands in these compounds.
