The complex cation which has two isomers is:

The complex cation which has two isomers is:

${[Co {(H_{2} O)}_{6}]}^{3 +}$
${[Co {({NH}_{3})}_{5} Cl]}^{2 +}$
${[Co {({NH}_{3})}_{5} {NO}_{2}]}^{2 +}$
${[Co {({NH}_{3})}_{5} Cl]}^{+}$

Solution

The complex shows linkage isomerism in the presence of ambidentate ligands.

${[Co {({NH}_{3})}_{5} {NO}_{2}]}^{2 +}$ shows linkage isomerism, because ${NO}_{2}^{-}$ ligand is ambidentate ligand.
