The structure described by DyAgSb2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal P4/nmm space group. Dy(1) is bonded in a 12-coordinate geometry to four equivalent Ag(1), four equivalent Sb(1), and four equivalent Sb(2) atoms. Ag(1) is bonded to four equivalent Dy(1), four equivalent Ag(1), and four equivalent Sb(2) atoms to form a mixture of face and corner-sharing AgDy4Ag4Sb4 cuboctahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to four equivalent Dy(1) and four equivalent Sb(1) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent Dy(1) and four equivalent Ag(1) atoms. is represented by the CIF card [CIF]
