Co Hg Os Os
Os2CoHg crystallizes in the monoclinic Cm space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 9-coordinate geometry to one Os(2), four equivalent Co(1), and four equivalent Hg(1) atoms. The Os(1)-Os(2) bond length is 2.27 Å. There are a spread of Os(1)-Co(1) bond distances ranging from 2.83-3.06 Å. There are a spread of Os(1)-Hg(1) bond distances ranging from 2.22-2.50 Å. In the second Os site, Os(2) is bonded in a 4-coordinate geometry to one Os(1), four equivalent Co(1), and four equivalent Hg(1) atoms. There are a spread of Os(2)-Co(1) bond distances ranging from 3.32-3.52 Å. There are a spread of Os(2)-Hg(1) bond distances ranging from 2.22-2.50 Å. Co(1) is bonded in a 13-coordinate geometry to four equivalent Os(1), four equivalent Os(2), four equivalent Co(1), and one Hg(1) atom. All Co(1)-Co(1) bond lengths are 2.92 Å. The Co(1)-Hg(1) bond length is 3.23 Å. Hg(1) is bonded in a distorted body-centered cubic geometry to four equivalent Os(1), four equivalent Os(2), and one Co(1) atom.
