What type of isomerism is exhibited by
$\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]\left[\mathrm{Cr}(\mathrm{CN})_6\right]$ and $\left[\mathrm{Cr}\left(\mathrm{NH}_3\right)_6\right]\left[\mathrm{Co}(\mathrm{CN})_6\right]$
Ionization isomerism
Linkage isomerism
Coordination isomerism
Solvate isomerism
Solution
When both ions in the compound are complex ions, and interchange of ligands results in coordination isomerism
