Hg Mo Au Au
MoAu2Hg is Copper structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MoAu2Hg cluster. Mo(1) is bonded in a single-bond geometry to one Au(2) atom. The Mo(1)-Au(2) bond length is 0.11 Å. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 2-coordinate geometry to one Au(2) and one Hg(1) atom. The Au(1)-Au(2) bond length is 0.73 Å. The Au(1)-Hg(1) bond length is 0.93 Å. In the second Au site, Au(2) is bonded in a distorted single-bond geometry to one Mo(1), one Au(1), and one Hg(1) atom. The Au(2)-Hg(1) bond length is 0.73 Å. Hg(1) is bonded in a distorted single-bond geometry to one Au(1) and one Au(2) atom.
