The complexes [ Co(NH _3)_6][ Cr(CN) _6] and [ Cr(NH _3)_6][ Co(CN) _6] are the examples of which type of isomerism?

NEET 2011 Chemistry question

The complexes and are the examples of which type of isomerism?

(1)Linkage isomerism
(2)Ionization isomerism
(3)Coordination isomerismCorrect
(4)Geometrical isomerism

Answer: (3)

Solution

Both compounds consist of a complex cation and a complex anion, and the two differ by an interchange of ligands between the two metal centres: is on Co in the first and on Cr in the second, while is on Cr in the first and on Co in the second. This exchange of ligands between the
