Coordination compound

Coordination compound is a type of chemical compound in which a central metal atom is surrounded by a group of ions or molecules, known as ligands. These ligands are attached to the central atom through coordinate covalent bonds, forming a coordination complex.

Structure of Coordination Compounds[edit | edit source]

The structure of a coordination compound involves a metal ion and its surrounding ligands. The number of ligands attached to the metal ion is called the coordination number. The coordination number can vary from 2 to 9, depending on the size and charge of the metal ion and ligands. The most common coordination numbers are 4 and 6.

Types of Ligands[edit | edit source]

Ligands can be classified into different types based on their charge and the number of donor atoms they have. Some common types of ligands include:

Monodentate ligands: These ligands have one donor atom and can form one coordinate bond with the metal ion.
Bidentate ligands: These ligands have two donor atoms and can form two coordinate bonds with the metal ion.
Polydentate ligands: These ligands have more than two donor atoms and can form multiple coordinate bonds with the metal ion.

Applications of Coordination Compounds[edit | edit source]

Coordination compounds have a wide range of applications in various fields such as:

Chemistry: They are used in the synthesis of many other compounds.
Medicine: Some coordination compounds are used as drugs to treat diseases like cancer.
Industry: They are used in the manufacturing of dyes, paints, and catalysts.
