Find the number of complexes, which shows cis and trans isomerism as well as optical isomerism.

[Pt(NH₃)₂Cl₂] , [Co(NH₃)₂(H₂O)₂Cl₂]Cl , [Co(NH₃)₃F₃] , [Ni(NH₃)₄Cl₂] , [Co(gly)₃] ,

[Co(en)₂Cl₂]Cl

The complexes showing both cis-trans and optical isomerism are:

1. $[C o (N H_{3})_{2} (H_{2} O)_{2} C l_{2}] Cl$ : The cis isomer is optically active.

2. $[C o (g l y)_{3}]$ : The cis isomer (facial) is optically active.

3. $[C o (e n)_{2} C l_{2}] Cl$ : The cis isomer is optically active.

Thus, there are 3 such complexes.
