OsHg2Bi crystallizes in the triclinic P1 space group. Os(1) is bonded in a 4-coordinate geometry to one Hg(2), two equivalent Hg(1), and one Bi(1) atom. The Os(1)-Hg(2) bond length is 3.17 Å. There is one shorter (2.77 Å) and one longer (2.98 Å) Os(1)-Hg(1) bond length. The Os(1)-Bi(1) bond length is 2.60 Å. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 4-coordinate geometry to two equivalent Os(1), one Hg(2), and one Bi(1) atom. The Hg(1)-Hg(2) bond length is 2.44 Å. The Hg(1)-Bi(1) bond length is 2.31 Å. In the second Hg site, Hg(2) is bonded in a 2-coordinate geometry to one Os(1), one Hg(1), and two equivalent Bi(1) atoms. There is one shorter (1.36 Å) and one longer (1.97 Å) Hg(2)-Bi(1) bond length. Bi(1) is bonded in a 4-coordinate geometry to one Os(1), one Hg(1), and two equivalent Hg(2) atoms.
