Pd3As crystallizes in the tetragonal I-4 space group. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 2-coordinate geometry to five equivalent Pd(3) and two equivalent As(1) atoms. In the second Pd site, Pd(2) is bonded in a 4-coordinate geometry to three equivalent Pd(3) and four equivalent As(1) atoms. In the third Pd site, Pd(3) is bonded in a 13-coordinate geometry to two equivalent Pd(3), three equivalent Pd(2), five equivalent Pd(1), and three equivalent As(1) atoms. As(1) is bonded in a 9-coordinate geometry to two equivalent Pd(1), three equivalent Pd(3), and four equivalent Pd(2) atoms.
Pd3As crystallizes in the tetragonal I-4 space group. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 2-coordinate geometry to five equivalent Pd(3) and two equivalent As(1) atoms. There are a spread of Pd(1)-Pd(3) bond distances ranging from 2.77-3.21 Å. There is one shorter (2.47 Å) and one longer (2.50 Å) Pd(1)-As(1) bond length. In the second Pd site, Pd(2) is bonded in a 4-coordinate geometry to three equivalent Pd(3) and four equivalent As(1) atoms. There are a spread of Pd(2)-Pd(3) bond distances ranging from 2.83-2.92 Å. There are a spread of Pd(2)-As(1) bond distances ranging from 2.56-2.68 Å. In the third Pd site, Pd(3) is bonded in a 13-coordinate geometry to two equivalent Pd(3), three equivalent Pd(2), five equivalent Pd(1), and three equivalent As(1) atoms. Both Pd(3)-Pd(3) bond lengths are 2.93 Å. There are a spread of Pd(3)-As(1) bond distances ranging from 2.48-2.66 Å. As(1) is bonded in a 9-coordinate geometry to two equivalent Pd(1), three equivalent Pd(3), and four equivalent Pd(2) atoms.
