Hg Hg Os Pb
OsHg2Pb crystallizes in the monoclinic Cm space group. Os(1) is bonded in a 4-coordinate geometry to three equivalent Hg(1) and four equivalent Hg(2) atoms. There is one shorter (3.30 Å) and two longer (3.47 Å) Os(1)-Hg(1) bond lengths. There are a spread of Os(1)-Hg(2) bond distances ranging from 2.30-2.75 Å. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 10-coordinate geometry to three equivalent Os(1), four equivalent Hg(1), and three equivalent Pb(1) atoms. All Hg(1)-Hg(1) bond lengths are 3.12 Å. There is one shorter (3.27 Å) and two longer (3.45 Å) Hg(1)-Pb(1) bond lengths. In the second Hg site, Hg(2) is bonded in a 5-coordinate geometry to four equivalent Os(1) and three equivalent Pb(1) atoms. There is one shorter (3.27 Å) and two longer (3.45 Å) Hg(2)-Pb(1) bond lengths. Pb(1) is bonded in a 10-coordinate geometry to three equivalent Hg(1), three equivalent Hg(2), and four equivalent Pb(1) atoms. All Pb(1)-Pb(1) bond lengths are 3.12 Å.
