The proof is in the powder: revealing structural peculiarities in the Yb3Rh4Sn13 structure type

Abstract

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[3 with combining macron]n; however, structural studies have led to the realization of disordered atomic sites, requiring lower symmetry models. We will review the low symmetry models required to describe the structural distortions in the related Yb3Rh4Sn13 structure type. In addition, we present the structure determination of a new analogue, Lu3Ir4Ge13, which adopts a new structural model in I41/amd.
