Chemistry - Coordination Chemistry Question with Solution | TestHub

The complex $[Co(en{)}_2(N{O}_2{)}_2]N{O}_3$ exhibits all four types of isomerism mentioned:

Ionization: The $N{O}_3^{-}$ ion outside the coordination sphere can exchange with an $N{O}_2^{-}$ ligand.

Linkage: The ambidentate $N{O}_2^{-}$ ligand can bind via Nitrogen (nitro) or Oxygen (nitrito).

Geometrical: The $[Co(en{)}_2(N{O}_2{)}_2{]}^{+}$ cation exists in both cis and trans configurations.

Optical: The cis isomer is non-superimposable on its mirror image, making it optically active.
