Materials Data on ErSn3 by Materials Project

Abstract

ErSn3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Er is bonded to twelve equivalent Sn atoms to form ErSn12 cuboctahedra that share corners with twelve equivalent ErSn12 cuboctahedra, edges with twenty-four equivalent SnEr4Sn8 cuboctahedra, faces with six equivalent ErSn12 cuboctahedra, and faces with twelve equivalent SnEr4Sn8 cuboctahedra. All Er–Sn bond lengths are 3.33 Å. Sn is bonded to four equivalent Er and eight equivalent Sn atoms to form distorted SnEr4Sn8 cuboctahedra that share corners with twelve equivalent SnEr4Sn8 cuboctahedra, edges with eight equivalent ErSn12 cuboctahedra, edges with sixteen equivalent SnEr4Sn8 cuboctahedra, faces with four equivalent ErSn12 cuboctahedra, and faces with fourteen equivalent SnEr4Sn8 cuboctahedra. All Sn–Sn bond lengths are 3.33 Å.
