Pd2As crystallizes in the hexagonal P-62m space group. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 4-coordinate geometry to six equivalent Pd(2), two equivalent As(1), and two equivalent As(2) atoms. In the second Pd site, Pd(2) is bonded in a 11-coordinate geometry to six equivalent Pd(1), one As(2), and four equivalent As(1) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 9-coordinate geometry to three equivalent Pd(1) and six equivalent Pd(2) atoms. In the second As site, As(2) is bonded in a 9-coordinate geometry to three equivalent Pd(2) and six equivalent Pd(1) atoms.

In the first Pd site, Pd(1) is bonded in a 4-coordinate geometry to six equivalent Pd(2), two equivalent As(1), and two equivalent As(2) atoms. There are two shorter (2.93 Å) and four longer (2.95 Å) Pd(1)-Pd(2) bond lengths. Both Pd(1)-As(1) bond lengths are 2.48 Å. Both Pd(1)-As(2) bond lengths are 2.55 Å. In the second Pd site, Pd(2) is bonded in a 11-coordinate geometry to six equivalent Pd(1), one As(2), and four equivalent As(1) atoms. The Pd(2)-As(2) bond length is 2.62 Å. All Pd(2)-As(1) bond lengths are 2.75 Å. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 9-coordinate geometry to three equivalent Pd(1) and six equivalent Pd(2) atoms. In the second As site, As(2) is bonded in a 9-coordinate geometry to three equivalent Pd(2) and six equivalent Pd(1) atoms.
