What type of isomerism is shown by the complex $[\text{Co(NH}_3)_6][\text{Cr(CN)}_6]$ ?

The given coordination compound $[\text{Co(NH}_3)_6][\text{Cr(CN)}_6]$ exhibits ionization isomerism.

**Explanation:** Ionization isomerism arises when two complexes have the same molecular formula but yield different ions in solution. In this case, the cationic complex $[\text{Co(NH}_3)_6]^{3+}$ and the anionic complex $[\text{Cr(CN)}_6]^{3-}$ could interchange their ligands under different conditions, leading to a different complex with distinct properties.
