Materials Data on U3Si by Materials Project

Abstract

U3Si is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. U is bonded to eight equivalent U and four equivalent Si atoms to form distorted UU8Si4 cuboctahedra that share corners with twelve equivalent UU8Si4 cuboctahedra, edges with eight equivalent SiU12 cuboctahedra, edges with sixteen equivalent UU8Si4 cuboctahedra, faces with four equivalent SiU12 cuboctahedra, and faces with fourteen equivalent UU8Si4 cuboctahedra. All U–U bond lengths are 3.01 Å. All U–Si bond lengths are 3.01 Å. Si is bonded to twelve equivalent U atoms to form SiU12 cuboctahedra that share corners with twelve equivalent SiU12 cuboctahedra, edges with twenty-four equivalent UU8Si4 cuboctahedra, faces with six equivalent SiU12 cuboctahedra, and faces with twelve equivalent UU8Si4 cuboctahedra.
