ThBi3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Th(1) is bonded to twelve equivalent Bi(1) atoms to form ThBi12 cuboctahedra that share corners with twelve equivalent Th(1)Bi12 cuboctahedra, edges with twenty-four equivalent Bi(1)Th4Bi8 cuboctahedra, faces with six equivalent Th(1)Bi12 cuboctahedra, and faces with twelve equivalent Bi(1)Th4Bi8 cuboctahedra. Bi(1) is bonded to four equivalent Th(1) and eight equivalent Bi(1) atoms to form distorted BiTh4Bi8 cuboctahedra that share corners with twelve equivalent Bi(1)Th4Bi8 cuboctahedra, edges with eight equivalent Th(1)Bi12 cuboctahedra, edges with sixteen equivalent Bi(1)Th4Bi8 cuboctahedra, faces with four equivalent Th(1)Bi12 cuboctahedra, and faces with fourteen equivalent Bi(1)Th4Bi8 cuboctahedra.
