Os3AuP crystallizes in the trigonal R3m space group. Os(1) is bonded in a 2-coordinate geometry to two equivalent Au(1) and one P(1) atom. There is one shorter (2.13 Å) and one longer (2.74 Å) Os(1)-Au(1) bond length. The Os(1)-P(1) bond length is 3.02 Å. Au(1) is bonded to six equivalent Os(1) atoms to form corner-sharing AuOs6 octahedra. The corner-sharing octahedra are not tilted. P(1) is bonded in a 3-coordinate geometry to three equivalent Os(1) atoms.
