Th e complexes [Co(NH3)6] [Cr (CN)6] and [Cr(NH3)6] [Co(CN)6] are the ...
Coordination isomerism occurs when cationic and anionic complexes of different metal ions are present in a salt. Interchange of ligand between the complexes give isomers e.g. [Co (NH3)6] [Cr (CN)6]  is an isomer of [Co (CN)6] [Cr (NH3)6]

Coordination isomerism is the type of isomerism exhibited by the complexes [Co(NH3)6] [Cr (CN)6] and [Cr(NH3)6] [Co(CN)6].

Explanation:
Coordination isomerism occurs when the coordination sphere of the metal ion in a complex is exchanged with a ligand from another complex ion. In other words, the central metal ion and the ligand interchange their positions between the two isomers.

In the given complexes, [Co(NH3)6] [Cr (CN)6] and [Cr(NH3)6] [Co(CN)6], the cobalt ion (Co2+) and the chromium ion (Cr3+) are present in both complexes, but they are bound to different ligands. In the first complex, cobalt is coordinated with ammonia ligands (NH3), while chromium is coordinated with cyanide ligands (CN-). In the second complex, chromium is coordinated with ammonia ligands, and cobalt is coordinated with cyanide ligands.

This interchange of ligands between the metal ions results in the formation of two different isomers, which are coordination isomers.

The coordination isomers can be represented as:
[Co(NH3)6] [Cr (CN)6] - cobalt is coordinated with ammonia ligands
[Cr(NH3)6] [Co(CN)6] - chromium is coordinated with ammonia ligands

These isomers have different chemical and physical properties because the ligands attached to the metal ion have different properties. The ligands can affect the color, magnetic behavior, and reactivity of the complex.

Therefore, the complexes [Co(NH3)6] [Cr (CN)6] and [Cr(NH3)6] [Co(CN)6] are examples of coordination isomerism.

Similar Class 12 Doubts

Read the passage given below and answer the following questions:The existence of coordination compounds with the same formula but different arrangements of the ligands was crucial in the development of coordination chemistry. Two or more compounds with the same formula but different arrangements of the atoms are called isomers. Isomers are compounds with the same molecular formula but different structural formulas and do not necessarily share similar properties. There are many different classes of isomers, like stereoisomers, enantiomers, and geometrical isomers. There are two main forms of isomerism: structural isomerism and stereoisomerism. The different chemical formulas in structural isomers are caused either by a difference in what ligands are bonded to the central atoms or how the individual ligands are bonded to the central atoms.The following questions are multiple choice questions. Choose the most appropriate answer:Q. What kind of isomerism exists between [Cr(H2O)6]Cl3 (violet) and [Cr(H2O)5Cl]Cl2.H2O (greyish green)?
