Materials Data on Rb2TlCl5O by Materials Project
Rb2TlOCl5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rb is bonded in a 7-coordinate geometry to seven Cl atoms. There are a spread of Rb–Cl bond distances ranging from 3.30–3.72 Å. Tl is bonded in a 6-coordinate geometry to one O and five Cl atoms. The Tl–O bond length is 2.31 Å. There are a spread of Tl–Cl bond distances ranging from 2.54–2.86 Å. O is bonded in a distorted single-bond geometry to one Tl and one Cl atom. The O–Cl bond length is 2.39 Å. There are four inequivalent Cl sites. In the first Cl site, Cl is bonded to four equivalent Rb and one Tl atom to form a mixture of distorted edge, corner, and face-sharing ClRb4Tl square pyramids. In the second Cl site, Cl is bonded to four equivalent Rb and one Tl atom to form a mixture of distorted edge, corner, and face-sharing ClRb4Tl square pyramids. In the third Cl site, Cl is bonded in a 4-coordinate geometry to two equivalent Rb, one Tl, and one O atom. In the fourth Cl site, Cl is bonded in a 1-coordinate geometry to two equivalent Rb and one Tl atom.
