Consider the square planar complex shown at right. Which of the structures below are geometric isomers of it?

The square planar complex

Geometric (cis-trans) isomers- different spatial arrangements of atoms or groups, relative to the central metal ion

Square planar complexes- square planar complexes are generally formed by metal ions with configuration which accept four ligands and form diamagnetic complexes

Structuresandare geometric (cis-trans) isomers of the shown square planar complex.

In structure , we can see that ligands and have exchanged their positions, so now, ligands and or ligands and are in trans positions. In structure , we can see that ligands and have exchanged their positions, so now, like in the structure , ligands and or ligands and are in trans positions. In structure E, we can see that ligand C came position of ligands A, B and C exchanged their positions, so now, ligands A and D and ligands and are in cis positions.
