Question

Which types of the following ligands are capable of linkage isomerism? Explain your answer.

${\mathbf{SCN}}^{\mathbf{-}}\mathbf{,}{\mathbf{N}}^{\mathbf{3}\mathbf{-}}\mathbf{,}{\mathbf{NO}}^{\mathbf{2}\mathbf{-}}\mathbf{,}{\mathbf{NH}}_{\mathbf{2}}{\mathbf{CH}}_{\mathbf{2}}{\mathbf{CH}}_{\mathbf{2}}{\mathbf{NH}}_{\mathbf{2}}\mathbf{,}{\mathbf{OCN}}^{\mathbf{-}}\mathbf{,}{\mathbf{I}}^{\mathbf{-}}$

Short answer

${\mathrm{SCN}}^{{-}^{}},{\mathrm{NO}}^{2-};{\mathrm{OCN}}^{-}$are capable of linkage isomerism.

Step-by-step solution

Step1:  Linkage isomerism definition

Coordination compounds having same compositions but differ bond connectivity of the ligand to the central metal is known as linkage isomers. Generally ambidentate ligands that have two different donor centers are capable of showing ligand isomerism.
