Materials Data on Cs3ErCl6 by Materials Project
Cs3ErCl6 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 10-coordinate geometry to ten Cl1- atoms. There are a spread of Cs–Cl bond distances ranging from 3.65–4.24 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 3.48–3.78 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 3.43–3.81 Å. There are two inequivalent Er3+ sites. In the first Er3+ site, Er3+ is bonded in an octahedral geometry to six Cl1- atoms. There are a spread of Er–Cl bond distances ranging from 2.61–2.66 Å. In the second Er3+ site, Er3+ is bonded in an octahedral geometry to six Cl1- atoms. There are four shorter (2.64 Å) and two longer (2.65 Å) Er–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 Er3+ atom. In the second Cl1- site, Cl1- is bonded in a 1-coordinate geometry to five Cs1+ and one Er3+ atom. In the third Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four Cs1+ and one Er3+ atom. In the fourth Cl1- site, Cl1- is bonded in a 1-coordinate geometry to five Cs1+ and one Er3+ atom. In the fifth Cl1- site, Cl1- is bonded in a distorted single-bond geometry to four Cs1+ and one Er3+ atom. In the sixth Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four Cs1+ and one Er3+ atom.
