ThTl3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Th(1) is bonded to twelve equivalent Tl(1) atoms to form ThTl12 cuboctahedra that share corners with twelve equivalent Th(1)Tl12 cuboctahedra, edges with twenty-four equivalent Tl(1)Th4Tl8 cuboctahedra, faces with six equivalent Th(1)Tl12 cuboctahedra, and faces with twelve equivalent Tl(1)Th4Tl8 cuboctahedra. Tl(1) is bonded to four equivalent Th(1) and eight equivalent Tl(1) atoms to form TlTh4Tl8 cuboctahedra that share corners with twelve equivalent Tl(1)Th4Tl8 cuboctahedra, edges with eight equivalent Th(1)Tl12 cuboctahedra, edges with sixteen equivalent Tl(1)Th4Tl8 cuboctahedra, faces with four equivalent Th(1)Tl12 cuboctahedra, and faces with fourteen equivalent Tl(1)Th4Tl8 cuboctahedra.
