Materials Data on Th3U by Materials Project
UTh3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. U is bonded to twelve equivalent Th atoms to form UTh12 cuboctahedra that share corners with twelve equivalent UTh12 cuboctahedra, edges with twenty-four equivalent ThTh8U4 cuboctahedra, faces with six equivalent UTh12 cuboctahedra, and faces with twelve equivalent ThTh8U4 cuboctahedra. All U–Th bond lengths are 3.48 Å. Th is bonded to four equivalent U and eight equivalent Th atoms to form ThTh8U4 cuboctahedra that share corners with twelve equivalent ThTh8U4 cuboctahedra, edges with eight equivalent UTh12 cuboctahedra, edges with sixteen equivalent ThTh8U4 cuboctahedra, faces with four equivalent UTh12 cuboctahedra, and faces with fourteen equivalent ThTh8U4 cuboctahedra. All Th–Th bond lengths are 3.48 Å.
