Materials Data on Rb2Hg2PdCl8 by Materials Project
Rb2PdHg2Cl8 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Rb1+ is bonded in a 10-coordinate geometry to ten Cl1- atoms. There are a spread of Rb–Cl bond distances ranging from 3.44–3.87 Å. Pd2+ is bonded in a square co-planar geometry to four equivalent Cl1- atoms. All Pd–Cl bond lengths are 2.33 Å. Hg2+ is bonded in a 2-coordinate geometry to five Cl1- atoms. There are a spread of Hg–Cl bond distances ranging from 2.35–3.27 Å. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and two equivalent Hg2+ atoms. In the second Cl1- site, Cl1- is bonded to three equivalent Rb1+, one Pd2+, and one Hg2+ atom to form a mixture of distorted corner, edge, and face-sharing ClRb3HgPd square pyramids. In the third Cl1- site, Cl1- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one Hg2+ atom.
