Question

An octahedral complex with molecular composition M.5NH 3 .Cl.SO 4 has two isomers, A and B. The solution of A gives a white precipitate with AgNO 3 solution and the solution of B gives white precipitate with BaCl 2 solution .The type of isomerism exhibited by the complex is :

The central metal atom M is in +3 oxidation state and ionisation isomers due to exchange of ligands outside & inside the co-ordination sphere are

$\underset{[A]}{[M {(N H_{3})}_{5} S O_{4}]} C l \overset{A g N O_{3}}{\to} \underset{w h i t e p p t}{A g C l_{(s)} ↓}$

$\underset{[B]}{[M {(N H_{3})}_{5} C l]} S O_{4} \overset{B a C l_{2}}{\to} \underset{w h i t e p p t}{B a S O_{4}_{(s)} ↓}$

[A] and [B] are ionisation isomers
