PrAgSb2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal P4/nmm space group. Pr(1) is bonded to four equivalent Ag(1), four equivalent Sb(1), and four equivalent Sb(2) atoms to form distorted PrAg4Sb8 cuboctahedra that share corners with four equivalent Pr(1)Ag4Sb8 cuboctahedra, edges with eight equivalent Pr(1)Ag4Sb8 cuboctahedra, edges with eight equivalent Ag(1)Pr4Ag4Sb4 cuboctahedra, faces with four equivalent Pr(1)Ag4Sb8 cuboctahedra, and faces with four equivalent Ag(1)Pr4Ag4Sb4 cuboctahedra. Ag(1) is bonded to four equivalent Pr(1), four equivalent Ag(1), and four equivalent Sb(2) atoms to form distorted AgPr4Ag4Sb4 cuboctahedra that share corners with four equivalent Ag(1)Pr4Ag4Sb4 cuboctahedra, edges with eight equivalent Pr(1)Ag4Sb8 cuboctahedra, faces with four equivalent Pr(1)Ag4Sb8 cuboctahedra, and faces with eight equivalent Ag(1)Pr4Ag4Sb4 cuboctahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to four equivalent Pr(1) and four equivalent Sb(1) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent Pr(1) and four equivalent Ag(1) atoms.
