PrPdSb2 crystallizes in the tetragonal P4/nmm space group. Pr(1) is bonded in a 10-coordinate geometry to four equivalent Pd(1), two equivalent Sb(1), and four equivalent Sb(2) atoms. Pd(1) is bonded in a 10-coordinate geometry to four equivalent Pr(1), two equivalent Sb(2), and four equivalent Sb(1) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 6-coordinate geometry to two equivalent Pr(1) and four equivalent Pd(1) atoms. In the second Sb site, Sb(2) is bonded in a 6-coordinate geometry to four equivalent Pr(1) and two equivalent Pd(1) atoms.
