Materials Data on Cs2TlCl5O by Materials Project
Cs2TlOCl5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cs is bonded in a 10-coordinate geometry to one O and nine Cl atoms. The Cs–O bond length is 3.31 Å. There are a spread of Cs–Cl bond distances ranging from 3.50–4.11 Å. Tl is bonded in a trigonal bipyramidal geometry to one O and four Cl atoms. The Tl–O bond length is 2.26 Å. There are two shorter (2.55 Å) and two longer (2.61 Å) Tl–Cl bond lengths. O is bonded in a distorted water-like geometry to two equivalent Cs, one Tl, and one Cl atom. The O–Cl bond length is 1.70 Å. There are four inequivalent Cl sites. In the first Cl site, Cl is bonded in a distorted single-bond geometry to four equivalent Cs and one Tl atom. In the second Cl site, Cl is bonded in a distorted single-bond geometry to four equivalent Cs and one Tl atom. In the third Cl site, Cl is bonded in a single-bond geometry to two equivalent Cs and one O atom. In the fourth Cl site, Cl is bonded to four equivalent Cs and one Tl atom to form a mixture of distorted corner and edge-sharing ClCs4Tl square pyramids.
