InBi is Tetraauricupride structured and crystallizes in the tetragonal P4/nmm space group. In(1) is bonded to four equivalent In(1) and eight equivalent Bi(1) atoms to form InIn4Bi8 cuboctahedra that share corners with twelve equivalent In(1)In4Bi8 cuboctahedra, edges with eight equivalent In(1)In4Bi8 cuboctahedra, edges with sixteen equivalent Bi(1)In8Bi4 cuboctahedra, faces with eight equivalent Bi(1)In8Bi4 cuboctahedra, and faces with ten equivalent In(1)In4Bi8 cuboctahedra. Bi(1) is bonded to eight equivalent In(1) and four equivalent Bi(1) atoms to form BiIn8Bi4 cuboctahedra that share corners with twelve equivalent Bi(1)In8Bi4 cuboctahedra, edges with eight equivalent Bi(1)In8Bi4 cuboctahedra, edges with sixteen equivalent In(1)In4Bi8 cuboctahedra, faces with eight equivalent In(1)In4Bi8 cuboctahedra, and faces with ten equivalent Bi(1)In8Bi4 cuboctahedra.
