AIPMTAIPMT 2006Coordination Compounds
Solution:
The compound $\left[ Co \left( NH _{3}\right)_{4}\left( NO _{2}\right)_{2}\right] Cl$ exhibits linkage, ionisation and geometrical isomerism. Hence,
(i) its linkage isomers are $\left[ Co \left( NH _{3}\right)_{4}\left( NO _{2}\right)_{2}\right] Cl$ and $\left[ Co \left( NH _{3}\right)_{4}( ONO )_{2}\right] Cl$
(ii) its ionisation isomers are
$\left[ Co \left( NH _{3}\right)_{4}\left( NO _{2}\right) Cl \right] NO _{2}$ and $\left[ Co \left( NH _{3}\right)_{4}\left( NO _{2}\right)_{2}\right] Cl$
(iii) its geometrical isomers are
