WebTranscript. Isomers are compounds of the same molecular formula but different molecular structures. There are four important types of isomers. Structural isomers atoms are bound in different orders while stereoisomers are bound in the same order but oriented differently. Geometric isomers involve different arrangement about a double bond. WebMore about Geometric Isomerism and Coordination Number. We find this type of isomerism in heteroleptic complexes. The main reason behind this would be the multiple geometric arrangements of ligands around the central metal atom. Coordination compounds with the coordination number of 4 and 6 mainly exhibit this type of isomerism.

Enantiomers, also known as optical isomers, are two stereoisomers that are related to each other by a reflection: they are mirror images of each other that are non-superposable. Human hands are a macroscopic analog of this. Every stereogenic center in one has the opposite configuration in the other.
