Pd4As crystallizes in the tetragonal I4/mmm 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) and four equivalent As(1) atoms. In the second Pd site, Pd(2) is bonded in a 8-coordinate geometry to four equivalent Pd(1) and four equivalent Pd(2) atoms. As(1) is bonded in a body-centered cubic geometry to eight equivalent Pd(1) atoms.
Pd4As crystallizes in the tetragonal I4/mmm 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) and four equivalent As(1) atoms. All Pd(1)-Pd(2) bond lengths are 2.82 Å. All Pd(1)-As(1) bond lengths are 2.65 Å. In the second Pd site, Pd(2) is bonded in a 8-coordinate geometry to four equivalent Pd(1) and four equivalent Pd(2) atoms. All Pd(2)-Pd(2) bond lengths are 2.75 Å. As(1) is bonded in a body-centered cubic geometry to eight equivalent Pd(1) atoms.
