Ag Ag Hg Pd
PdAg2Hg crystallizes in the monoclinic Pm space group. Pd(1) is bonded in a single-bond geometry to one Ag(1) and one Hg(1) atom. The Pd(1)-Ag(1) bond length is 0.24 Å. The Pd(1)-Hg(1) bond length is 2.81 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a single-bond geometry to one Pd(1) and one Ag(2) atom. The Ag(1)-Ag(2) bond length is 2.58 Å. In the second Ag site, Ag(2) is bonded to one Ag(1), four equivalent Ag(2), and one Hg(1) atom to form AgAg5Hg octahedra that share corners with four equivalent Ag(2)Ag5Hg octahedra, edges with four equivalent Ag(2)Ag5Hg octahedra, and edges with four equivalent Hg(1)AgHg4Pd octahedra. The corner-sharing octahedra are not tilted. All Ag(2)-Ag(2) bond lengths are 2.92 Å. The Ag(2)-Hg(1) bond length is 3.04 Å. Hg(1) is bonded to one Pd(1), one Ag(2), and four equivalent Hg(1) atoms to form HgAgHg4Pd octahedra that share corners with four equivalent Hg(1)AgHg4Pd octahedra, edges with four equivalent Ag(2)Ag5Hg octahedra, and edges with four equivalent Hg(1)AgHg4Pd octahedra. The corner-sharing octahedra are not tilted. All Hg(1)-Hg(1) bond lengths are 2.92 Å.
