Solution
The correct option is D[PtCl2Br2]2− (square planar) The complex [PtCl2Br2]2− (square planar) can exist as diastereoisomers. It exists in cis form and trans form. Diastereomerism occurs when two or more stereoisomers of a compound have different configurations at one or more (but not all) of the equivalent (related) stereocenters and are not mirror images of each other.
