Materials Data on AsPd4 by Materials Project
Pd4As crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 8-coordinate geometry to four equivalent Pd and four equivalent As atoms. All Pd–Pd bond lengths are 2.82 Å. All Pd–As bond lengths are 2.65 Å. In the second Pd site, Pd is bonded in a 8-coordinate geometry to eight Pd atoms. All Pd–Pd bond lengths are 2.75 Å. As is bonded in a body-centered cubic geometry to eight equivalent Pd atoms.
