Compounds adopting the Yb3Rh4Sn13 structure type have drawn attention because of the revelation of exotic states such as heavy fermion behavior, superconductivity, charge density wave, and quantum critical behavior. The prototypical structure has historically been modeled with a primitive cubic space group, Pm-3n; however, structural studies have led to the realization of disordered atomic sites, requiring lower symmetry models. Low symmetry models required to describe the structural distortions in the related Yb3Rh4Sn13 structure type and the implications for future directions for discovery of highly correlated systems will be highlighted.
