Materials Data on HoSn3 by Materials Project

Abstract

HoSn3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ho is bonded to twelve equivalent Sn atoms to form HoSn12 cuboctahedra that share corners with twelve equivalent HoSn12 cuboctahedra, edges with twenty-four equivalent SnHo4Sn8 cuboctahedra, faces with six equivalent HoSn12 cuboctahedra, and faces with twelve equivalent SnHo4Sn8 cuboctahedra. All Ho–Sn bond lengths are 3.33 Å. Sn is bonded to four equivalent Ho and eight equivalent Sn atoms to form distorted SnHo4Sn8 cuboctahedra that share corners with twelve equivalent SnHo4Sn8 cuboctahedra, edges with eight equivalent HoSn12 cuboctahedra, edges with sixteen equivalent SnHo4Sn8 cuboctahedra, faces with four equivalent HoSn12 cuboctahedra, and faces with fourteen equivalent SnHo4Sn8 cuboctahedra. All Sn–Sn bond lengths are 3.33 Å.
