Pr2AuP3 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 9-coordinate geometry to two equivalent Au(1), one P(1), two equivalent P(3), and four equivalent P(2) atoms. In the second Pr site, Pr(2) is bonded in a 6-coordinate geometry to three equivalent Au(1), three equivalent P(1), and three equivalent P(3) atoms. Au(1) is bonded in a 9-coordinate geometry to two equivalent Pr(1), three equivalent Pr(2), two equivalent P(1), and two equivalent P(2) atoms. There are three inequivalent P sites. In the first P site, P(1) is bonded to one Pr(1), three equivalent Pr(2), and two equivalent Au(1) atoms to form distorted PPr4Au2 octahedra that share corners with five equivalent P(3)Pr5P octahedra, edges with three equivalent P(3)Pr5P octahedra, and edges with four equivalent P(1)Pr4Au2 octahedra. The corner-sharing octahedral tilt angles range from 16-67°. In the second P site, P(2) is bonded in a 7-coordinate geometry to four equivalent Pr(1), two equivalent Au(1), and one P(3) atom. In the third P site, P(3) is bonded to two equivalent Pr(1), three equivalent Pr(2), and one P(2) atom to form distorted PPr5P octahedra that share corners with five equivalent P(1)Pr4Au2 octahedra, edges with three equivalent P(1)Pr4Au2 octahedra, and edges with four equivalent P(3)Pr5P octahedra. The corner-sharing octahedral tilt angles range from 16-67°.

In the first Pr site, Pr(1) is bonded in a 9-coordinate geometry to two equivalent Au(1), one P(1), two equivalent P(3), and four equivalent P(2) atoms. Both Pr(1)-Au(1) bond lengths are 3.31 Å. The Pr(1)-P(1) bond length is 2.95 Å. Both Pr(1)-P(3) bond lengths are 2.96 Å. There are two shorter (3.04 Å) and two longer (3.12 Å) Pr(1)-P(2) bond lengths. In the second Pr site, Pr(2) is bonded in a 6-coordinate geometry to three equivalent Au(1), three equivalent P(1), and three equivalent P(3) atoms. There is one shorter (3.27 Å) and two longer (3.42 Å) Pr(2)-Au(1) bond lengths. There are two shorter (2.95 Å) and one longer (2.97 Å) Pr(2)-P(1) bond length. There are two shorter (3.01 Å) and one longer (3.02 Å) Pr(2)-P(3) bond length. Au(1) is bonded in a 9-coordinate geometry to two equivalent Pr(1), three equivalent Pr(2), two equivalent P(1), and two equivalent P(2) atoms. Both Au(1)-P(1) bond lengths are 2.45 Å.
