Materials Data on TlAuCl4 by Materials Project
AuTlCl4 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Au3+ is bonded in a square co-planar geometry to four Cl1- atoms. There are two shorter (2.32 Å) and two longer (2.33 Å) Au–Cl bond lengths. Tl1+ is bonded in a distorted q6 geometry to ten Cl1- atoms. There are a spread of Tl–Cl bond distances ranging from 3.44–3.65 Å. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Au3+ and two equivalent Tl1+ atoms. In the second Cl1- site, Cl1- is bonded in a 1-coordinate geometry to one Au3+ and three equivalent Tl1+ atoms.
