The number of isomers possible for  is:

Canvas Classes · Accepted Answer

Strategy:
 Identify geometrical limitations for a generic square planar complex  and account for the ambidentate nature of the  ligand.

Step 1: Identify geometric isomerism
In , the ethylenediamine (en) is a bidentate ligand. It can only occupy two adjacent (cis) positions on the square plane due to structural strain. Therefore, the two  ligands must also be cis to each other. No trans-isomer is structurally possible.

Step 2: Identify linkage isomerism
The  ligand is ambidentate, binding via N
