Cs2PdHgCl6 crystallizes in the tetragonal I4/mmm space group. Cs(1) is bonded to four equivalent Cl(1) and eight equivalent Cl(2) atoms to form a mixture of face and corner-sharing CsCl12 cuboctahedra. Pd(1) is bonded in a square co-planar geometry to four equivalent Cl(2) atoms. Hg(1) is bonded in a distorted linear geometry to two equivalent Cl(1) atoms. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted single-bond geometry to four equivalent Cs(1) and one Hg(1) atom. In the second Cl site, Cl(2) is bonded in a distorted single-bond geometry to four equivalent Cs(1) and one Pd(1) atom.
