As we learnt in

Stereoisomers -

Stereoisomers have the same chemical formula and chemical bonds but they have different special arrangement

-

$\left [ Co(en)_{2} \right ] Cl$, possible isomers are:

Since, this product is chiral, so it's mirror image will also be a possible isomer.

This one is not chiral. So, no mirror image isomer.

$\therefore$ total possible isomers = $2+1 = 3$
