Materials Data on USn by Materials Project

Abstract

USn crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. U is bonded to six equivalent U and six equivalent Sn atoms to form UU6Sn6 cuboctahedra that share corners with eighteen equivalent UU6Sn6 cuboctahedra, edges with six equivalent UU6Sn6 cuboctahedra, edges with twelve equivalent SnU6Sn6 cuboctahedra, faces with eight equivalent UU6Sn6 cuboctahedra, and faces with twelve equivalent SnU6Sn6 cuboctahedra. All U–U bond lengths are 3.11 Å. All U–Sn bond lengths are 3.28 Å. Sn is bonded to six equivalent U and six equivalent Sn atoms to form SnU6Sn6 cuboctahedra that share corners with eighteen equivalent SnU6Sn6 cuboctahedra, edges with six equivalent SnU6Sn6 cuboctahedra, edges with twelve equivalent UU6Sn6 cuboctahedra, faces with eight equivalent SnU6Sn6 cuboctahedra, and faces with twelve equivalent UU6Sn6 cuboctahedra. All Sn–Sn bond lengths are 3.11 Å.
