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.
