CeAgSb2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal P4/nmm space group. Ce(1) is bonded to four equivalent Ag(1), four equivalent Sb(1), and four equivalent Sb(2) atoms to form distorted CeAg4Sb8 cuboctahedra that share corners with four equivalent Ce(1)Ag4Sb8 cuboctahedra, edges with eight equivalent Ce(1)Ag4Sb8 cuboctahedra, edges with eight equivalent Ag(1)Ce4Ag4Sb4 cuboctahedra, faces with four equivalent Ce(1)Ag4Sb8 cuboctahedra, and faces with four equivalent Ag(1)Ce4Ag4Sb4 cuboctahedra. Ag(1) is bonded to four equivalent Ce(1), four equivalent Ag(1), and four equivalent Sb(2) atoms to form distorted AgCe4Ag4Sb4 cuboctahedra that share corners with four equivalent Ag(1)Ce4Ag4Sb4 cuboctahedra, edges with eight equivalent Ce(1)Ag4Sb8 cuboctahedra, faces with four equivalent Ce(1)Ag4Sb8 cuboctahedra, and faces with eight equivalent Ag(1)Ce4Ag4Sb4 cuboctahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent Sb(1) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent Ag(1) atoms.
