Pd5SbAs crystallizes in the cubic Fd-3m space group. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 8-coordinate geometry to four equivalent Pd(2), two equivalent Sb(1), and two equivalent As(1) atoms. In the second Pd site, Pd(2) is bonded in a 3-coordinate geometry to six equivalent Pd(1) and three equivalent Sb(1) atoms. Sb(1) is bonded to six equivalent Pd(1) and six equivalent Pd(2) atoms to form SbPd12 cuboctahedra that share edges with six equivalent As(1)Pd6 octahedra and faces with six equivalent Sb(1)Pd12 cuboctahedra. As(1) is bonded to six equivalent Pd(1) atoms to form AsPd6 octahedra that share corners with six equivalent As(1)Pd6 octahedra and edges with six equivalent Sb(1)Pd12 cuboctahedra. The corner-sharing octahedral tilt angles are 54°.
