Square planar geometry does not allow for chiral centers, and therefore optical isomers are not possible. Geometric isomers are possible if there are two different ligands located in the cis or trans position to each other, and linkage isomers are possible if one of the ligands is a bidentate ligand that can form different bonds with the central metal ion. Coordination isomers can occur if there are two different coordination entities bonded to each other through an interchange of ligands.
