Materials Data on RbHo2Cl7 by Materials Project

RbHo2Cl7 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rb1+ is bonded in a 10-coordinate geometry to ten Cl1- atoms. There are a spread of Rb–Cl bond distances ranging from 3.50–3.71 Å. There are two inequivalent Ho3+ sites. In the first Ho3+ site, Ho3+ is bonded to seven Cl1- atoms to form a mixture of distorted edge and face-sharing HoCl7 pentagonal bipyramids. There are a spread of Ho–Cl bond distances ranging from 2.69–2.79 Å. In the second Ho3+ site, Ho3+ is bonded to seven Cl1- atoms to form a mixture of distorted edge and face-sharing HoCl7 pentagonal bipyramids. There are a spread of Ho–Cl bond distances ranging from 2.69–2.73 Å. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 2-coordinate geometry to two equivalent Rb1+ and two Ho3+ atoms. In the second Cl1- site, Cl1- is bonded in a distorted L-shaped geometry to one Rb1+ and two Ho3+ atoms. In the third Cl1- site, Cl1- is bonded in a distorted trigonal non-coplanar geometry to one Rb1+ and two Ho3+ atoms. In the fourth Cl1- site, Cl1- is bonded in a 2-coordinate geometry to two equivalent Rb1+ and two Ho3+ atoms.

Materials Data on Rb3HoCl6 by Materials Project

Rb3HoCl6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded to twelve equivalent Cl1- atoms to form distorted RbCl12 cuboctahedra that share corners with twelve equivalent RbCl12 cuboctahedra, faces with six equivalent RbCl12 cuboctahedra, faces with four equivalent RbCl6 octahedra, and faces with four equivalent HoCl6 octahedra. All Rb–Cl bond lengths are 4.07 Å. In the second Rb1+ site, Rb1+ is bonded to six equivalent Cl1- atoms to form RbCl6 octahedra that share corners with six equivalent HoCl6 octahedra and faces with eight equivalent RbCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Rb–Cl bond lengths are 3.12 Å. Ho3+ is bonded to six equivalent Cl1- atoms to form HoCl6 octahedra that share corners with six equivalent RbCl6 octahedra and faces with eight equivalent RbCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ho–Cl bond lengths are 2.62 Å. Cl1- is bonded in a linear geometry to five Rb1+ and one Ho3+ atom.
