Ba3Th is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ba(1) is bonded to eight equivalent Ba(1) and four equivalent Th(1) atoms to form distorted BaBa8Th4 cuboctahedra that share corners with twelve equivalent Ba(1)Ba8Th4 cuboctahedra, edges with eight equivalent Th(1)Ba12 cuboctahedra, edges with sixteen equivalent Ba(1)Ba8Th4 cuboctahedra, faces with four equivalent Th(1)Ba12 cuboctahedra, and faces with fourteen equivalent Ba(1)Ba8Th4 cuboctahedra. Th(1) is bonded to twelve equivalent Ba(1) atoms to form ThBa12 cuboctahedra that share corners with twelve equivalent Th(1)Ba12 cuboctahedra, edges with twenty-four equivalent Ba(1)Ba8Th4 cuboctahedra, faces with six equivalent Th(1)Ba12 cuboctahedra, and faces with twelve equivalent Ba(1)Ba8Th4 cuboctahedra.
