Question

Draw the geometric, linkage, and ionization isomers for \(\left( {CoC{l_5}CN} \right)(CN)\)

Short answer

Isomers are the chemical species which have the same molecular formula but different arrangement of atoms or ligands in space.

Step-by-step solution

of 3: Explanation

• Geometric isomers are isomers in which the orientation of atoms in the space is relative to each other which lead to different physical and chemical properties.
• Linkage isomers are isomers in which the bonding to the central metal atom is observed for two different atoms belonging to the same ligand
• Ionisation isomers are the isomers in which the anionic ligands are replaced by the counter ion in the inner coordination space.

of 3: Diagrammatic representation

There are 8 isomers for \(\left( {{\rm{CoC}}{{\rm{l}}_5}{\rm{CN}}} \right)({\rm{CN}})\)

of 3: Variations of isomers

• There are different variation of these isomers:
• a) Only geometric isomer:\(1)\).
• b) Only linkage isomer:\(2)\).
• c) Geometric and linkage isomer: \(3),{\rm{ }}4)\)and\(5)\).
• d) Geometric and ionization isomer: \(7)\)and \(8).\)
• e) Linkage and ionization isomer: \(2)\)and\(5)\).
• f) Geometrical, linkage and ionization isomer: \(2),{\rm{ }}3),{\rm{ }}5),{\rm{ }}6).\)

Result

There are \(8\) isomers of this molecule which have different variations.
