The structure described by LuCuSb2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal P4/nmm space group. Lu(1) is bonded to four equivalent Cu(1), four equivalent Sb(1), and four equivalent Sb(2) atoms to form LuCu4Sb8 cuboctahedra that share corners with four equivalent Lu(1)Cu4Sb8 cuboctahedra, edges with eight equivalent Lu(1)Cu4Sb8 cuboctahedra, edges with eight equivalent Cu(1)Lu4Cu4Sb4 cuboctahedra, faces with four equivalent Lu(1)Cu4Sb8 cuboctahedra, and faces with four equivalent Cu(1)Lu4Cu4Sb4 cuboctahedra. Cu(1) is bonded to four equivalent Lu(1), four equivalent Cu(1), and four equivalent Sb(2) atoms to form distorted CuLu4Cu4Sb4 cuboctahedra that share corners with four equivalent Cu(1)Lu4Cu4Sb4 cuboctahedra, edges with eight equivalent Lu(1)Cu4Sb8 cuboctahedra, faces with four equivalent Lu(1)Cu4Sb8 cuboctahedra, and faces with eight equivalent Cu(1)Lu4Cu4Sb4 cuboctahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to four equivalent Lu(1) and four equivalent Sb(1) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent Lu(1) and four equivalent Cu(1) atoms. is represented by the CIF card [CIF]
