Compounds having the same chemical formula but different physical and chemical properties due to the different structural arrangements are called isomers. This phenomenon is known as isomerism.
Coordination compounds exhibit two major types of isomerism, namely (A) structural isomerism and (B) stereoisomerism (space isomerism). Each of these is further classified as shown below.
(A) Structural isomerism
- Coordination isomerism
- Ionisation isomerism
- Hydrate or Solvate isomerism
- Linkage isomerism
- Ligand Isomerism
(B) Stereoisomerism
- Geometrical isomerism
- Optical isomerism
