Q. Number of possible isomers for the complex $[Co(en)_2Cl_2] Cl$ will be : (en = ethylenediamine)
AIPMTAIPMT 2015Coordination Compounds
Solution:
$[Co(en)_2 Cl_2]Cl$
Possible isomers -
(i) Geometrical isomers
(ii) In trans form plane of symmetry present, so trans form is optically inactive but cis is optically active.
Total number of stereoisomer = 2+1 =3
