K Hg Hg Os
KOsHg2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KOsHg2 clusters. K(1) is bonded in a 3-coordinate geometry to one Os(1) and two equivalent Hg(1) atoms. The K(1)-Os(1) bond length is 1.81 Å. Both K(1)-Hg(1) bond lengths are 1.60 Å. Os(1) is bonded in a 3-coordinate geometry to one K(1) and two equivalent Hg(1) atoms. Both Os(1)-Hg(1) bond lengths are 1.60 Å. Hg(1) is bonded in a 2-coordinate geometry to one K(1) and one Os(1) atom.
