Al Zn Hg Os
OsHgZnAl crystallizes in the trigonal R3m space group. Os(1) is bonded in a 1-coordinate geometry to three equivalent Zn(1) and one Al(1) atom. All Os(1)-Zn(1) bond lengths are 2.72 Å. The Os(1)-Al(1) bond length is 2.14 Å. Hg(1) is bonded in a distorted linear geometry to four equivalent Zn(1) and one Al(1) atom. There is one shorter (2.14 Å) and three longer (3.03 Å) Hg(1)-Zn(1) bond lengths. The Hg(1)-Al(1) bond length is 2.32 Å. Zn(1) is bonded in a 10-coordinate geometry to three equivalent Os(1), four equivalent Hg(1), and three equivalent Al(1) atoms. All Zn(1)-Al(1) bond lengths are 2.72 Å. Al(1) is bonded in a distorted linear geometry to one Os(1), one Hg(1), and three equivalent Zn(1) atoms.
