Hg As As P
HgAs2P is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one HgAs2P cluster. Hg(1) is bonded in a distorted single-bond geometry to one As(2) and one P(1) atom. The Hg(1)-As(2) bond length is 1.52 Å. The Hg(1)-P(1) bond length is 0.68 Å. There are two inequivalent As sites. In the first As site, As(1) is bonded in a distorted single-bond geometry to one As(2) and one P(1) atom. The As(1)-As(2) bond length is 1.52 Å. The As(1)-P(1) bond length is 0.68 Å. In the second As site, As(2) is bonded in a 2-coordinate geometry to one Hg(1) and one As(1) atom. P(1) is bonded in an L-shaped geometry to one Hg(1) and one As(1) atom.
