Rb2PdHg2Cl8 crystallizes in the monoclinic C2/m space group. Rb(1) is bonded in a 10-coordinate geometry to two equivalent Cl(1), two equivalent Cl(3), and six equivalent Cl(2) atoms. Pd(1) is bonded in a square co-planar geometry to four equivalent Cl(2) atoms. Hg(1) is bonded in a linear geometry to one Cl(1) and one Cl(3) atom. There are three inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to two equivalent Rb(1) and one Hg(1) atom. In the second Cl site, Cl(2) is bonded in a 4-coordinate geometry to three equivalent Rb(1) and one Pd(1) atom. In the third Cl site, Cl(3) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one Hg(1) atom.
Rb2PdHg2Cl8 crystallizes in the monoclinic C2/m space group. Rb(1) is bonded in a 10-coordinate geometry to two equivalent Cl(1), two equivalent Cl(3), and six equivalent Cl(2) atoms.
