PrCuSb2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal P4/nmm space group. Pr(1) is bonded to four equivalent Cu(1), four equivalent Sb(1), and four equivalent Sb(2) atoms to form a mixture of edge, corner, and face-sharing PrCu4Sb8 cuboctahedra. Cu(1) is bonded in a 4-coordinate geometry to four equivalent Pr(1) and four equivalent Sb(1) atoms. 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 Cu(1) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent Pr(1) and four equivalent Sb(2) atoms.
