KOsAu2 crystallizes in the triclinic P1 space group. K(1) is bonded in a distorted single-bond geometry to one Os(1), one Au(1), and one Au(2) atom. The K(1)-Os(1) bond length is 3.38 Å. The K(1)-Au(1) bond length is 2.46 Å. The K(1)-Au(2) bond length is 1.56 Å. Os(1) is bonded to one K(1), two equivalent Os(1), two equivalent Au(1), and two equivalent Au(2) atoms to form a mixture of distorted corner and edge-sharing OsKOs2Au4 pentagonal bipyramids. Both Os(1)-Os(1) bond lengths are 2.73 Å. There is one shorter (3.06 Å) and one longer (3.27 Å) Os(1)-Au(1) bond length. There is one shorter (3.06 Å) and one longer (3.27 Å) Os(1)-Au(2) bond length. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a distorted single-bond geometry to one K(1) and two equivalent Os(1) atoms. In the second Au site, Au(2) is bonded in a single-bond geometry to one K(1) and two equivalent Os(1) atoms.
