LuIn3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Lu(1) is bonded to twelve equivalent In(1) atoms to form LuIn12 cuboctahedra that share corners with twelve equivalent Lu(1)In12 cuboctahedra, edges with twenty-four equivalent In(1)Lu4In8 cuboctahedra, faces with six equivalent Lu(1)In12 cuboctahedra, and faces with twelve equivalent In(1)Lu4In8 cuboctahedra. In(1) is bonded to four equivalent Lu(1) and eight equivalent In(1) atoms to form distorted InLu4In8 cuboctahedra that share corners with twelve equivalent In(1)Lu4In8 cuboctahedra, edges with eight equivalent Lu(1)In12 cuboctahedra, edges with sixteen equivalent In(1)Lu4In8 cuboctahedra, faces with four equivalent Lu(1)In12 cuboctahedra, and faces with fourteen equivalent In(1)Lu4In8 cuboctahedra.
