Isomerism in Coordination Compounds

1. What is Coordination Compound?

Coordination Compounds are chemical compounds in which the central atom is a transition metal and negative or neutral ligands are attached more than the normal valency of the central atom.

2. What are Isomers?

Isomers are chemical compounds that have the same molecular formula but different molecular structures.

3. What are the Two different types of Isomers?

The two different types of isomers are Structural Isomers and Stereo Isomers.

4. What are Cis and Trans Isomers?

Cis and Trans isomers are the types of Stereoisomers. In Cis-isomers the two similar bonds with the central atom are on the same side of the central atom while in trans-isomer the two similar bonds are on the different sides of the central atom.

5. What are Ligands?

Ligands are the negative or neutral atoms attached to the central atom in a number more than the usual valency of the central atom.

6. What is Coordination Complex?

The Central Atom together with ligands are called the Coordination Complex.

7. What is Water of Crystallization?

The number of water molecules attached to the crystal of a molecule is called Water of Crystallization. For Example in CuSO4.5H2O, the water number of water molecules attached to the crystal is 5, hence the Water of Crystallization for Copper Sulfate Pentahydrate is 5.

Isomerism in Coordination Compounds as the name suggests explores the concept of Isomerism in Coordination Compounds i.e., generally compounds formed by d-block elements. Isomerism is the phenomenon of exhibiting different molecular structures by the compounds with same molecular formula. The phenomenon of isomerism is quite significant in hydrocarbons however it is of no less importance in coordination compounds. Coordination Compounds are those chemical compounds in which a group of anions is attached to a central metal atom via covalent bonds. Coordinate compounds are also called coordinate complexes. The coordinate compounds having the same molecular formula but different arrangements of ligands are called isomers of coordination compounds and the phenomenon exhibited is called Isomerism in Coordination Compounds. In this article, we will learn about different types of isomerism exhibited by Coordination Compounds in detail.
