Materials Data on Cs2YbCl5 by Materials Project

Abstract

Cs2YbCl5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 10-coordinate geometry to ten Cl1- atoms. There are a spread of Cs–Cl bond distances ranging from 3.68–4.01 Å. In the second Cs1+ site, Cs1+ is bonded in a 10-coordinate geometry to ten Cl1- atoms. There are a spread of Cs–Cl bond distances ranging from 3.56–3.82 Å. Yb3+ is bonded to six Cl1- atoms to form corner-sharing YbCl6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are a spread of Yb–Cl bond distances ranging from 2.67–2.71 Å. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted single-bond geometry to four Cs1+ and one Yb3+ atom. In the second Cl1- site, Cl1- is bonded in a distorted single-bond geometry to four Cs1+ and one Yb3+ atom. In the third Cl1- site, Cl1- is bonded to four Cs1+ and one Yb3+ atom to form distorted corner-sharing ClCs4Yb square pyramids. In the fourth Cl1- site, Cl1- is bonded in a distorted linear geometry to four Cs1+ and two equivalent Yb3+ atoms.
