What is the role of crystal structure to decide whether the material is topological insulator (TI) or not?

The chalcogenide compounds Bi2Se3, Bi2Te3 and Sb2Te3 are crystallize in Rhombohedral structure (S.G: R -3m, Z=3) and all the three compounds are ambient topological insulator. However, Sb2Se3 in...
