Cu Cu Hg Bi
Cu2HgBi is Copper structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Cu2HgBi cluster. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a single-bond geometry to one Bi(1) atom. The Cu(1)-Bi(1) bond length is 0.90 Å. In the second Cu site, Cu(2) is bonded in a distorted bent 150 degrees geometry to one Hg(1) and one Bi(1) atom. The Cu(2)-Hg(1) bond length is 1.92 Å. The Cu(2)-Bi(1) bond length is 2.19 Å. Hg(1) is bonded in a 1-coordinate geometry to one Cu(2) atom. Bi(1) is bonded in a single-bond geometry to one Cu(1) and one Cu(2) atom.
