The CdS3 skeleton of the anion in monoclinic (Ph4P)[Cd(S{O}CPh)3] has a near-planar structure, but among the three crystallographically different anions in the structure of rhombohedral (Ph4P)[Cd(S{O}CPh)3] there are both planar and uniquely pyramidal CdS3 skeletons. Thus, the [Cd(S{O}CPh)3]- anion provides a new example of polytopal isomerism.
