[CO(NH3)2(NO2)2]NO3​

Answer 1

Answer:

The complex [Co(NH

3

)

4

(NO

2

)

2

](NO

3

)] has ten isomers. They include geometrical, ionization and linkage isomers.

NO

3

and NO

2

groups can be either inside or outside the coordination sphere. This gives ionization isomers. NO

2

group can coordinate through N or O atom. This gives linkage isomerism. cis and trans isomers give geometrical isomers.
