Name the type of isomerism exhibited by the following isomers:
[Pt(NH

_{3}

)

_{4}

][PtCl

_{6}

] and [Pt(NH

_{3}

)

_{4}

_{2}

][PtCl

_{4}

]

Answer: Coordination isomerism.

Solution

Both compounds contain a cationic and an anionic complex; the ligands (NH

_{3}

and Cl

^{-}

) are interchanged between the two coordination spheres.
Such interchange of ligands between cationic and anionic entities is coordination isomerism.
