    Which one of the following is an example of co-ordination isomerism?

    A) \[[Co{{(N{{H}_{3}})}_{5}}Br]S{{O}_{4}}\]and\[[Co{{(N{{H}_{3}})}_{5}}S{{O}_{4}}]Br\]

    B) \[[Co{{(N{{H}_{3}})}_{5}}N{{O}_{2}}]C{{l}_{2}}\]and \[[Co{{(N{{H}_{3}})}_{5}}ONO]C{{l}_{2}}\]

    C) \[[Cr{{({{H}_{2}}O)}_{6}}]C{{l}_{3}}\]and\[[Cr{{({{H}_{2}}O)}_{5}}]Cl]C{{l}_{2}}{{H}_{2}}O\]

    D) \[[Co{{(N{{H}_{3}})}_{6}}][Cr{{(CN)}_{6}}\]and\[[Cr{{(N{{H}_{3}})}_{6}}][Co{{(CN)}_{6}}]\]

    Correct Answer: D

    Solution :

    This type of isomerism occurs when both action and anion are complex. The isomerism is caused by that interchange of ligands between the two complex ion of the same complex. Examples are (i) \[[Co{{(N{{H}_{3}})}_{6}}][Cr{{(CN)}_{6}}]\]and\[[Cr{{(N{{H}_{3}})}_{6}}][Co{{(CN)}_{6}}]\] (ii) \[[Co{{(N{{H}_{3}})}_{6}}][Cr{{({{C}_{2}}{{O}_{4}})}_{3}}]\]and\[[Cr{{(N{{H}_{3}})}_{6}}][Co{{({{C}_{2}}{{O}_{4}})}_{3}}]\]
