Pd2BiAs crystallizes in the trigonal R3m space group. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a distorted trigonal planar geometry to four equivalent Bi(1) atoms. There are three shorter (2.78 Å) and one longer (3.61 Å) Pd(1)-Bi(1) bond length. In the second Pd site, Pd(2) is bonded in a single-bond geometry to three equivalent Bi(1) and one As(1) atom. All Pd(2)-Bi(1) bond lengths are 2.83 Å. The Pd(2)-As(1) bond length is 0.89 Å. Bi(1) is bonded in a 10-coordinate geometry to three equivalent Pd(2), four equivalent Pd(1), and three equivalent As(1) atoms. All Bi(1)-As(1) bond lengths are 2.78 Å. As(1) is bonded in a single-bond geometry to one Pd(2) and three equivalent Bi(1) atoms.
