# Ionization isomerism in coordination compounds

Ionization isomerism is defined as complexes which have same empirical formula but ionize to different ions in solution.

Consider the complex $$\ce{[Pt(NH3)4Cl2]I2}$$. The other possible ionization isomers are: $$\ce{[Pt(NH3)4I2]Cl2}$$ and $$\ce{[Pt(NH3)4ICl]ICl}$$.

But I have not come across the complexes similar to the last one with two different anions outside the coordination sphere. So, do these sort of complexes exist?

Moreover, what can be the IUPAC name for this compound?

tetraamminechloridoiodoplatinum(IV) chlorineiodine seems wrong.
