Two or more different compounds having the same molecular formula are called isomers and the phenomenon is called isomerism. Isomerism arises due to specific spatial dispositions of the atoms in a molecule. Due to covalence of M-L bonds, many types of isomers occur in co-ordination compounds. However, compared to organic compounds, relatively few inorganic compounds exhibit isomerism. .
