Q. The complexes [Co(NH₃)₆][Cr(CN)₆] and [Cr(NH₃)₆][Co(CN)₆] are the examples of which type of isomerism?
A) Geometrical isomerism
B) Linkage isomerism
C) Ionization isomerism
D) Coordination isomerism
Explanation
[Solution from source] Both compounds have the same formula, but the ligands are exchanged between the cobalt and chromium centres of the cationic and anionic complexes. This is coordination isomerism. Ionisation isomerism would involve exchange of an ion between the coordination sphere and the counter-ion. Answer (4).
