Hg Pd Pd Cl
Pd2HgCl is alpha Niobium phosphide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Pd2HgCl clusters. 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 Cl(1) atom. The Pd(1)-Hg(1) bond length is 2.04 Å. The Pd(1)-Cl(1) bond length is 0.71 Å. In the second Pd site, Pd(2) is bonded in a single-bond geometry to one Hg(1) atom. The Pd(2)-Hg(1) bond length is 1.77 Å. Hg(1) is bonded in a 2-coordinate geometry to one Pd(1) and one Pd(2) atom. Cl(1) is bonded in a single-bond geometry to one Pd(1) atom.
