OsHg2Cl crystallizes in the monoclinic Cm space group. Os(1) is bonded in a 10-coordinate geometry to two equivalent Os(1) and eight equivalent Hg(1) atoms. Both Os(1)-Os(1) bond lengths are 2.95 Å. There are a spread of Os(1)-Hg(1) bond distances ranging from 2.75-3.01 Å. Hg(1) is bonded in a 8-coordinate geometry to four equivalent Os(1) and four equivalent Cl(1) atoms. There are a spread of Hg(1)-Cl(1) bond distances ranging from 2.75-3.01 Å. Cl(1) is bonded in a distorted body-centered cubic geometry to eight equivalent Hg(1) atoms.
