Q. Define Ionisation Isomerism?
Ionisation Isomerism: when coordinated ions exchange positions with ions present in the lattice position, we get ionisation isomers. Thus compounds having the same chemical composition give different ions in solution For example, a compound [Co(NH3)5BrS04 which is violet in colour yields [co(NH3)5Br2+ and SO2-4ions in solution, whereas a red isomer of the compound [co(NH3)5Br2produces [CO(NH3)5SO4+ and Br ions in solution. Other examples are:
[Co(en)2(N02)CIlN02 and [Co(en) 2 (N02]CI
[Pt(NH3)5cI2IBr2 and [Pt(NH3)4Br2]Cl2 etc.
