The complex ion . `[M(en)Br_(2)I_(2)]^(-1)`, has two optical isomers. Their correct configurations are:

The complex [Co(en)_2Cl_2]^+ has 3/4 geometrical and optical isomers.

For the complex ion [F(en)_(2)CI_(2)]^(+) write the hybridization type and magnetic behavior. Draw one of the geometrical isomer of the complex ion which is optically active. [A tomic No, :Fe=26]

Assertion : The complex ion trans- [Co(en)_2Cl_2]^+ is optically active. Reason: It is an octahedral complex.
