Os2AuP crystallizes in the monoclinic Cm space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded to one Os(2), six equivalent Os(1), and one Au(1) atom to form distorted OsOs7Au hexagonal bipyramids that share corners with six equivalent Os(1)Os7Au hexagonal bipyramids, edges with six equivalent Au(1)POsAu6 hexagonal bipyramids, and edges with twelve equivalent Os(1)Os7Au hexagonal bipyramids. The Os(1)-Os(2) bond length is 2.81 Å. All Os(1)-Os(1) bond lengths are 2.84 Å. The Os(1)-Au(1) bond length is 3.21 Å. In the second Os site, Os(2) is bonded in a single-bond geometry to one Os(1) and one P(1) atom. The Os(2)-P(1) bond length is 0.04 Å. Au(1) is bonded to one Os(1), six equivalent Au(1), and one P(1) atom to form distorted AuPOsAu6 hexagonal bipyramids that share corners with six equivalent Au(1)POsAu6 hexagonal bipyramids, edges with six equivalent Os(1)Os7Au hexagonal bipyramids, and edges with twelve equivalent Au(1)POsAu6 hexagonal bipyramids. All Au(1)-Au(1) bond lengths are 2.84 Å. The Au(1)-P(1) bond length is 2.85 Å. P(1) is bonded in a single-bond geometry to one Os(2) and one Au(1) atom.
