Question
Which of the following statements are correct for the complex [Co(NH3)4(Cl) (NO2)]Cl ?
1. Cobalt is in +III oxidation state involving d2sp3 hybridisation.
2. Cobalt is in +III oxidation state involving sp3d2 hybridisation.
3. It shows ionisation as well as linkage isomerism.
4. It also shows geometrical isomerism.

4. It also shows geometrical isomerism.
Options
A.1, 3 and 4 only
B.2, 3 and 4 only
C.1 and 4 only
D.2 and 4 only
Solution
Statements 1, 3 and 4 are correct but 2 is incorrect.
3d6 configuration of Co3+ has greater CFSE and this favours the d2sp3 hybridisation. NO2- is ambidentate ligand and Cl- and NO2- can exchange as counter ion ; so complex can show ionisation as well as linkage isomerism. The complex also exists in cis and trans isomeric forms.
