SrOsHg2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrOsHg2 clusters. Sr(1) is bonded in a 3-coordinate geometry to one Os(1) and two equivalent Hg(1) atoms. The Sr(1)-Os(1) bond length is 1.65 Å. Both Sr(1)-Hg(1) bond lengths are 1.46 Å. Os(1) is bonded in a 3-coordinate geometry to one Sr(1) and two equivalent Hg(1) atoms. Both Os(1)-Hg(1) bond lengths are 1.46 Å. Hg(1) is bonded in a 2-coordinate geometry to one Sr(1) and one Os(1) atom.
