Question

Indicate the types of isomerism exhibited by the following complexes :
(i) `[Co(NH_3)_5(NO_2)]^(2+)`
(ii) `[Co(en)_3]Cl_3` (en= ethylene diamine)
(iii) `[Pt(NH_3)_2Cl_2]`

Answer 1

Linkage isomerism is the existence of co-ordination compounds hat have the same composition differing with the connectivity of metal to a ligand.
(ii)
(iii) Geometrical Isomerism : This type of isomerism arises in heteroleptic compelxes due to different possible geometric arrangements of the ligands.
