Au2P3 crystallizes in the monoclinic C2/m space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a distorted linear geometry to two equivalent P(1) and two equivalent P(2) atoms. In the second Au site, Au(2) is bonded in a linear geometry to two equivalent P(2) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 5-coordinate geometry to two equivalent Au(1), one P(1), and two equivalent P(2) atoms. In the second P site, P(2) is bonded to one Au(1), one Au(2), one P(1), and one P(2) atom to form corner-sharing PP2Au2 tetrahedra.
Au2P3 crystallizes in the monoclinic C2/m space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a distorted linear geometry to two equivalent P(1) and two equivalent P(2) atoms. Both Au(1)-P(1) bond lengths are 3.09 Å. Both Au(1)-P(2) bond lengths are 2.34 Å. In the second Au site, Au(2) is bonded in a linear geometry to two equivalent P(2) atoms. Both Au(2)-P(2) bond lengths are 2.35 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 5-coordinate geometry to two equivalent Au(1), one P(1), and two equivalent P(2) atoms. The P(1)-P(1) bond length is 2.25 Å. Both P(1)-P(2) bond lengths are 2.21 Å. In the second P site, P(2) is bonded to one Au(1), one Au(2), one P(1), and one P(2) atom to form corner-sharing PP2Au2 tetrahedra. The P(2)-P(2) bond length is 2.20 Å.
