UPdSb2 crystallizes in the tetragonal P4/nmm space group. U(1) is bonded to four equivalent Pd(1), four equivalent Sb(1), and four equivalent Sb(2) atoms to form a mixture of face, corner, and edge-sharing USb8Pd4 cuboctahedra. Pd(1) is bonded in a 8-coordinate geometry to four equivalent U(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 U(1) and four 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(2) atoms.
