Materials Data on Rb2TmCl5 by Materials Project

Abstract

Rb2TmCl5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 10-coordinate geometry to ten Cl1- atoms. There are a spread of Rb–Cl bond distances ranging from 3.47–3.89 Å. In the second Rb1+ site, Rb1+ is bonded in a 10-coordinate geometry to ten Cl1- atoms. There are a spread of Rb–Cl bond distances ranging from 3.38–3.73 Å. Tm3+ is bonded to six Cl1- atoms to form corner-sharing TmCl6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are a spread of Tm–Cl bond distances ranging from 2.53–2.69 Å. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four Rb1+ and one Tm3+ atom. In the second Cl1- site, Cl1- is bonded in a distorted single-bond geometry to four Rb1+ and one Tm3+ atom. In the third Cl1- site, Cl1- is bonded in a 5-coordinate geometry to four Rb1+ and one Tm3+ atom. In the fourth Cl1- site, Cl1- is bonded in a distorted linear geometry to four Rb1+ and two equivalent Tm3+ atoms.
