Materials Data on Hf3Sn by Materials Project

Abstract

Hf3Sn is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Hf is bonded to eight equivalent Hf and four equivalent Sn atoms to form distorted HfHf8Sn4 cuboctahedra that share corners with twelve equivalent HfHf8Sn4 cuboctahedra, edges with eight equivalent SnHf12 cuboctahedra, edges with sixteen equivalent HfHf8Sn4 cuboctahedra, faces with four equivalent SnHf12 cuboctahedra, and faces with fourteen equivalent HfHf8Sn4 cuboctahedra. All Hf–Hf bond lengths are 3.14 Å. All Hf–Sn bond lengths are 3.14 Å. Sn is bonded to twelve equivalent Hf atoms to form SnHf12 cuboctahedra that share corners with twelve equivalent SnHf12 cuboctahedra, edges with twenty-four equivalent HfHf8Sn4 cuboctahedra, faces with six equivalent SnHf12 cuboctahedra, and faces with twelve equivalent HfHf8Sn4 cuboctahedra.
