Materials Data on Cs8Na4YHo3Cl24 by Materials Project

Abstract

Cs8Na4Ho3YCl24 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are four inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded to twelve Cl1- atoms to form CsCl12 cuboctahedra that share corners with twelve CsCl12 cuboctahedra, faces with six CsCl12 cuboctahedra, faces with four equivalent NaCl6 octahedra, and faces with four HoCl6 octahedra. All Cs–Cl bond lengths are 3.86 Å. In the second Cs1+ site, Cs1+ is bonded to twelve Cl1- atoms to form CsCl12 cuboctahedra that share corners with twelve CsCl12 cuboctahedra, faces with six CsCl12 cuboctahedra, a faceface with one YCl6 octahedra, faces with three equivalent HoCl6 octahedra, and faces with four NaCl6 octahedra. There are three shorter (3.85 Å) and nine longer (3.86 Å) Cs–Cl bond lengths. In the third Cs1+ site, Cs1+ is bonded to twelve Cl1- atoms to form CsCl12 cuboctahedra that share corners with twelve CsCl12 cuboctahedra, faces with six CsCl12 cuboctahedra, a faceface with one HoCl6 octahedra, faces with three equivalent YCl6 octahedra, and faces with four equivalent NaCl6 octahedra. There are three shorter (3.85 Å) and nine longer (3.86 Å) Cs–Cl bond lengths. In the fourth Cs1+ site, Cs1+ is bonded to twelve Cl1- atoms to form CsCl12 cuboctahedra that share corners with twelve CsCl12 cuboctahedra, faces with six CsCl12 cuboctahedra, faces with four NaCl6 octahedra, and faces with four HoCl6 octahedra. All Cs–Cl bond lengths are 3.86 Å. There are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six Cl1- atoms to form NaCl6 octahedra that share corners with six HoCl6 octahedra and faces with eight CsCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Na–Cl bond lengths are 2.82 Å. In the second Na1+ site, Na1+ is bonded to six Cl1- atoms to form NaCl6 octahedra that share corners with three equivalent HoCl6 octahedra, corners with three equivalent YCl6 octahedra, and faces with eight CsCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There are three shorter (2.80 Å) and three longer (2.82 Å) Na–Cl bond lengths. There are two inequivalent Ho3+ sites. In the first Ho3+ site, Ho3+ is bonded to six Cl1- atoms to form HoCl6 octahedra that share corners with six NaCl6 octahedra and faces with eight CsCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ho–Cl bond lengths are 2.63 Å. In the second Ho3+ site, Ho3+ is bonded to six equivalent Cl1- atoms to form HoCl6 octahedra that share corners with six equivalent NaCl6 octahedra and faces with eight CsCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ho–Cl bond lengths are 2.63 Å. Y3+ is bonded to six equivalent Cl1- atoms to form YCl6 octahedra that share corners with six equivalent NaCl6 octahedra and faces with eight CsCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Y–Cl bond lengths are 2.65 Å. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted linear geometry to four Cs1+, one Na1+, and one Ho3+ atom. In the second Cl1- site, Cl1- is bonded in a distorted linear geometry to four Cs1+, one Na1+, and one Ho3+ atom. In the third Cl1- site, Cl1- is bonded in a distorted linear geometry to four Cs1+, one Na1+, and one Y3+ atom. In the fourth Cl1- site, Cl1- is bonded in a distorted linear geometry to four Cs1+, one Na1+, and one Ho3+ atom.
