U2PdSb4 crystallizes in the tetragonal P-4m2 space group. U(1) is bonded in a 10-coordinate geometry to two equivalent Pd(1), two equivalent Sb(2), two equivalent Sb(3), and four equivalent Sb(1) atoms. Pd(1) is bonded in a distorted body-centered cubic geometry to four equivalent U(1) and four equivalent Sb(1) atoms. There are three inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 6-coordinate geometry to four equivalent U(1) and two equivalent Pd(1) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent Sb(3) atoms. In the third Sb site, Sb(3) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent Sb(2) atoms.
