Hg Hg P Rh
RhHg2P crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one RhHg2P cluster. Rh(1) is bonded in a 2-coordinate geometry to one Hg(2) and one P(1) atom. The Rh(1)-Hg(2) bond length is 1.93 Å. The Rh(1)-P(1) bond length is 2.08 Å. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a distorted single-bond geometry to one P(1) atom. The Hg(1)-P(1) bond length is 1.93 Å. In the second Hg site, Hg(2) is bonded in a distorted single-bond geometry to one Rh(1) atom. P(1) is bonded in a 2-coordinate geometry to one Rh(1) and one Hg(1) atom.
