Hg Hg Os Au
OsAuHg2 crystallizes in the triclinic P1 space group. Os(1) is bonded in a 2-coordinate geometry to one Au(1), one Hg(2), and two equivalent Hg(1) atoms. The Os(1)-Au(1) bond length is 2.64 Å. The Os(1)-Hg(2) bond length is 1.94 Å. There is one shorter (3.06 Å) and one longer (3.25 Å) Os(1)-Hg(1) bond length. Au(1) is bonded in a single-bond geometry to one Os(1), one Hg(1), and one Hg(2) atom. The Au(1)-Hg(1) bond length is 2.74 Å. The Au(1)-Hg(2) bond length is 1.13 Å. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 6-coordinate geometry to two equivalent Os(1), one Au(1), one Hg(2), and two equivalent Hg(1) atoms. The Hg(1)-Hg(2) bond length is 2.50 Å. Both Hg(1)-Hg(1) bond lengths are 2.87 Å. In the second Hg site, Hg(2) is bonded in a distorted single-bond geometry to one Os(1), one Au(1), and one Hg(1) atom.
