Cu Hg Br
CuHgBr is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CuHgBr cluster. Cu(1) is bonded in a distorted single-bond geometry to one Br(1) atom. The Cu(1)-Br(1) bond length is 1.17 Å. Hg(1) is bonded in a single-bond geometry to one Br(1) atom. The Hg(1)-Br(1) bond length is 1.36 Å. Br(1) is bonded in a distorted L-shaped geometry to one Cu(1) and one Hg(1) atom.
