Sn Hg Hg P
Hg2SnP is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Hg2SnP cluster. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a single-bond geometry to one Sn(1) atom. The Hg(1)-Sn(1) bond length is 1.85 Å. In the second Hg site, Hg(2) is bonded in a distorted single-bond geometry to one Sn(1) and one P(1) atom. The Hg(2)-Sn(1) bond length is 2.02 Å. The Hg(2)-P(1) bond length is 1.14 Å. Sn(1) is bonded in a distorted L-shaped geometry to one Hg(1) and one Hg(2) atom. P(1) is bonded in a single-bond geometry to one Hg(2) atom.
