Materials Data on Cs3CeCl6 by Materials Project

Abstract

Cs3CeCl6 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of Cs–Cl bond distances ranging from 3.69–4.08 Å. In the second Cs1+ site, Cs1+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of Cs–Cl bond distances ranging from 3.45–3.86 Å. In the third Cs1+ site, Cs1+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of Cs–Cl bond distances ranging from 3.47–3.89 Å. There are two inequivalent Ce3+ sites. In the first Ce3+ site, Ce3+ is bonded in an octahedral geometry to six Cl1- atoms. There are a spread of Ce–Cl bond distances ranging from 2.73–2.78 Å. In the second Ce3+ site, Ce3+ is bonded in an octahedral geometry to six Cl1- atoms. There are two shorter (2.76 Å) and four longer (2.78 Å) Ce–Cl bond lengths. There are six inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four Cs1+ and one Ce3+ atom. In the second Cl1- site, Cl1- is bonded in a 5-coordinate geometry to four Cs1+ and one Ce3+ atom. In the third Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four Cs1+ and one Ce3+ atom. In the fourth Cl1- site, Cl1- is bonded to four Cs1+ and one Ce3+ atom to form distorted face-sharing ClCs4Ce square pyramids. In the fifth Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four Cs1+ and one Ce3+ atom. In the sixth Cl1- site, Cl1- is bonded in a 5-coordinate geometry to four Cs1+ and one Ce3+ atom.
