ThIn3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Th(1) is bonded to twelve equivalent In(1) atoms to form ThIn12 cuboctahedra that share corners with twelve equivalent Th(1)In12 cuboctahedra, edges with twenty-four equivalent In(1)Th4In8 cuboctahedra, faces with six equivalent Th(1)In12 cuboctahedra, and faces with twelve equivalent In(1)Th4In8 cuboctahedra. In(1) is bonded to four equivalent Th(1) and eight equivalent In(1) atoms to form distorted InTh4In8 cuboctahedra that share corners with twelve equivalent In(1)Th4In8 cuboctahedra, edges with eight equivalent Th(1)In12 cuboctahedra, edges with sixteen equivalent In(1)Th4In8 cuboctahedra, faces with four equivalent Th(1)In12 cuboctahedra, and faces with fourteen equivalent In(1)Th4In8 cuboctahedra.
