Materials Data on Sn3Bi by Materials Project

Abstract

BiSn3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Sn is bonded to eight equivalent Sn and four equivalent Bi atoms to form SnSn8Bi4 cuboctahedra that share corners with twelve equivalent SnSn8Bi4 cuboctahedra, edges with eight equivalent BiSn12 cuboctahedra, edges with sixteen equivalent SnSn8Bi4 cuboctahedra, faces with four equivalent BiSn12 cuboctahedra, and faces with fourteen equivalent SnSn8Bi4 cuboctahedra. All Sn–Sn bond lengths are 3.46 Å. All Sn–Bi bond lengths are 3.46 Å. Bi is bonded to twelve equivalent Sn atoms to form BiSn12 cuboctahedra that share corners with twelve equivalent BiSn12 cuboctahedra, edges with twenty-four equivalent SnSn8Bi4 cuboctahedra, faces with six equivalent BiSn12 cuboctahedra, and faces with twelve equivalent SnSn8Bi4 cuboctahedra.
