Q. Illustrate about square planar complexes?
For square planar complexes Mu, Ma3b or Mab3 where a and b etc., are monodentate ligands, again the geometrical isomerism is not possible. However, square planar complexes of the type Ma2b2, Ma2bc. Mabcd and M(AA) 2, M(AB) 2-where AA and AB represent symmetrical and unsymmetrical chelating agents -do give geometrical isomers.
