    The complexes \[[Co{{(N{{H}_{3}})}_{6}}][R{{(CN)}_{6}}]\] and \[[Cr{{(N{{H}_{3}})}_{6}}][Co{{(CN)}_{6}}]\] are the examples of which type of isomerism?     [AIPMT (S) 2011]

    A) Ionisation isomerism

    B) Co-ordination isomerism

    C) Geometrical isomerism

    D) Linkage isomerism

    Correct Answer: B

    Solution :

    [b] The complexes \[[Co{{(N{{H}_{3}})}_{6}}[Cr{{(CN)}_{6}}]\]and \[[Cr{{(N{{H}_{3}})}_{6}}[Co{{(CN)}_{6}}]\] are the examples of co-ordination isomerism’s. This isomerism occurs only in those complexes in which both cation and anion are complex. It occurs due to exchange of ligands between cation and anion.
