BiIn3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. In(1) is bonded to eight equivalent In(1) and four equivalent Bi(1) atoms to form InIn8Bi4 cuboctahedra that share corners with twelve equivalent In(1)In8Bi4 cuboctahedra, edges with eight equivalent Bi(1)In12 cuboctahedra, edges with sixteen equivalent In(1)In8Bi4 cuboctahedra, faces with four equivalent Bi(1)In12 cuboctahedra, and faces with fourteen equivalent In(1)In8Bi4 cuboctahedra. Bi(1) is bonded to twelve equivalent In(1) atoms to form BiIn12 cuboctahedra that share corners with twelve equivalent Bi(1)In12 cuboctahedra, edges with twenty-four equivalent In(1)In8Bi4 cuboctahedra, faces with six equivalent Bi(1)In12 cuboctahedra, and faces with twelve equivalent In(1)In8Bi4 cuboctahedra.
