ThEu3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Th(1) is bonded to twelve equivalent Eu(1) atoms to form ThEu12 cuboctahedra that share corners with twelve equivalent Th(1)Eu12 cuboctahedra, edges with twenty-four equivalent Eu(1)Eu8Th4 cuboctahedra, faces with six equivalent Th(1)Eu12 cuboctahedra, and faces with twelve equivalent Eu(1)Eu8Th4 cuboctahedra. Eu(1) is bonded to four equivalent Th(1) and eight equivalent Eu(1) atoms to form EuEu8Th4 cuboctahedra that share corners with twelve equivalent Eu(1)Eu8Th4 cuboctahedra, edges with eight equivalent Th(1)Eu12 cuboctahedra, edges with sixteen equivalent Eu(1)Eu8Th4 cuboctahedra, faces with four equivalent Th(1)Eu12 cuboctahedra, and faces with fourteen equivalent Eu(1)Eu8Th4 cuboctahedra.
