Materials Data on Cs2DyCl5 by Materials Project

Cs2DyCl5 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 3.55–3.82 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 3.64–3.98 Å. Dy3+ is bonded to six Cl1- atoms to form corner-sharing DyCl6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are a spread of Dy–Cl bond distances ranging from 2.58–2.77 Å. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted linear geometry to four Cs1+ and two equivalent Dy3+ atoms. In the second Cl1- site, Cl1- is bonded in a distorted single-bond geometry to four Cs1+ and one Dy3+ atom. In the third Cl1- site, Cl1- is bonded in a 5-coordinate geometry to four Cs1+ and one Dy3+ atom. In the fourth Cl1- site, Cl1- is bonded in a distorted single-bond geometry to four Cs1+ and one Dy3+ atom.

Materials Data on CsDy2Cl7 by Materials Project

CsDy2Cl7 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cs1+ is bonded in a 10-coordinate geometry to ten Cl1- atoms. There are a spread of Cs–Cl bond distances ranging from 3.59–3.86 Å. There are two inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded to seven Cl1- atoms to form a mixture of distorted edge and face-sharing DyCl7 pentagonal bipyramids. There are a spread of Dy–Cl bond distances ranging from 2.71–2.80 Å. In the second Dy3+ site, Dy3+ is bonded to seven Cl1- atoms to form a mixture of distorted edge and face-sharing DyCl7 pentagonal bipyramids. There are a spread of Dy–Cl bond distances ranging from 2.71–2.75 Å. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 2-coordinate geometry to two equivalent Cs1+ and two Dy3+ atoms. In the second Cl1- site, Cl1- is bonded in a distorted L-shaped geometry to one Cs1+ and two Dy3+ atoms. In the third Cl1- site, Cl1- is bonded in a distorted trigonal non-coplanar geometry to one Cs1+ and two Dy3+ atoms. In the fourth Cl1- site, Cl1- is bonded in a distorted water-like geometry to two equivalent Cs1+ and two Dy3+ atoms.
