Question

What are ionization isomers? Give an example.

✓

Answer

Ionisation isomers : The coordination compounds having same molecular composition but differ in the compositions of coordination (or inner) sphere and outer sphere and produce different ions on ionisation in the solution are called ionisation isomers.
For example, Pentaamminesulphatocobalt
(III) bromide $[Co(NH_3)_5SO_4]$ Br, Pentaamminebromocobalt
(III) sulphate $[Co(NH_3)_5Br] SO_4.$
