Hg2CdP crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Hg2CdP cluster. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 1-coordinate geometry to one Hg(2) atom. The Hg(1)-Hg(2) bond length is 1.08 Å. In the second Hg site, Hg(2) is bonded in a distorted bent 120 degrees geometry to one Hg(1) and one P(1) atom. The Hg(2)-P(1) bond length is 2.66 Å. Cd(1) is bonded in a single-bond geometry to one P(1) atom. The Cd(1)-P(1) bond length is 0.81 Å. P(1) is bonded in a single-bond geometry to one Hg(2) and one Cd(1) atom.
