Hg Hg As Os
OsHg2As crystallizes in the triclinic P1 space group. Os(1) is bonded in a 12-coordinate geometry to two equivalent Os(1), two equivalent Hg(2), four equivalent Hg(1), and four equivalent As(1) atoms. Both Os(1)-Os(1) bond lengths are 3.11 Å. There is one shorter (3.24 Å) and one longer (3.35 Å) Os(1)-Hg(2) bond length. There are a spread of Os(1)-Hg(1) bond distances ranging from 2.78-3.09 Å. There are a spread of Os(1)-As(1) bond distances ranging from 2.57-3.23 Å. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 10-coordinate geometry to four equivalent Os(1), two equivalent Hg(1), and four equivalent Hg(2) atoms. Both Hg(1)-Hg(1) bond lengths are 3.11 Å. There are a spread of Hg(1)-Hg(2) bond distances ranging from 2.57-3.23 Å. In the second Hg site, Hg(2) is bonded in a 12-coordinate geometry to two equivalent Os(1), two equivalent Hg(2), four equivalent Hg(1), and four equivalent As(1) atoms. Both Hg(2)-Hg(2) bond lengths are 3.11 Å. There are a spread of Hg(2)-As(1) bond distances ranging from 2.78-3.09 Å. As(1) is bonded in a 8-coordinate geometry to four equivalent Os(1) and four equivalent Hg(2) atoms.
