Materials Data on Tl2Hg2PdCl8 by Materials Project

Abstract

PdHg2Tl2Cl8 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. 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 distorted linear geometry to four Cl1- atoms. There are a spread of Hg–Cl bond distances ranging from 2.34–3.23 Å. Tl1+ is bonded in a 10-coordinate geometry to ten Cl1- atoms. There are a spread of Tl–Cl bond distances ranging from 3.34–3.77 Å. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 1-coordinate geometry to one Pd2+, one Hg2+, and three equivalent Tl1+ atoms. In the second Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Hg2+ and two equivalent Tl1+ atoms. In the third Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Hg2+ and two equivalent Tl1+ atoms.
