Materials Data on Sn3Ge by Materials Project

Abstract

Sn3Ge 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 Ge atoms to form SnSn8Ge4 cuboctahedra that share corners with twelve equivalent SnSn8Ge4 cuboctahedra, edges with eight equivalent GeSn12 cuboctahedra, edges with sixteen equivalent SnSn8Ge4 cuboctahedra, faces with four equivalent GeSn12 cuboctahedra, and faces with fourteen equivalent SnSn8Ge4 cuboctahedra. All Sn–Sn bond lengths are 3.31 Å. All Sn–Ge bond lengths are 3.31 Å. Ge is bonded to twelve equivalent Sn atoms to form GeSn12 cuboctahedra that share corners with twelve equivalent GeSn12 cuboctahedra, edges with twenty-four equivalent SnSn8Ge4 cuboctahedra, faces with six equivalent GeSn12 cuboctahedra, and faces with twelve equivalent SnSn8Ge4 cuboctahedra.
