Pd2HgCd is Copper structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Pd2HgCd cluster. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a single-bond geometry to one Hg(1) and one Cd(1) atom. The Pd(1)-Hg(1) bond length is 0.55 Å. The Pd(1)-Cd(1) bond length is 1.26 Å. In the second Pd site, Pd(2) is bonded in a distorted single-bond geometry to one Hg(1) and one Cd(1) atom. The Pd(2)-Hg(1) bond length is 0.84 Å. The Pd(2)-Cd(1) bond length is 1.36 Å. Hg(1) is bonded in a 3-coordinate geometry to one Pd(1), one Pd(2), and one Cd(1) atom. The Hg(1)-Cd(1) bond length is 1.16 Å. Cd(1) is bonded in a 3-coordinate geometry to one Pd(1), one Pd(2), and one Hg(1) atom.
