title: Materials Data on Cs8Na4Y3HoCl24 by Materials Project

description: Cs8Na4HoY3Cl24 is (Cubic) Perovskite-derived structured and crystallizes in the orthorhombic Pmmm space group. The structure is three-dimensional. there are three 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 NaCl6 octahedra, and faces with four YCl6 octahedra. There are ten shorter (3.85 Å) and two longer (3.86 Å) Cs–Cl bond lengths. 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 HoCl6 octahedra, faces with three YCl6 octahedra, and faces with four NaCl6 octahedra. There are ten shorter (3.85 Å) and two 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, faces with two equivalent HoCl6 octahedra, faces with two equivalent YCl6 octahedra, and faces with four NaCl6 octahedra. There are ten shorter (3.85 Å) and two longer (3.86 Å) Cs–Cl bond lengths. There are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six Cl1- atoms to form NaCl6 octahedra that share corners with six YCl6 octahedra and faces with eight CsCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Na–Cl bond lengths are 2.80 Å. In the second Na1+ site, Na1+ is bonded to six Cl1- atoms to form NaCl6 octahedra that share corners with two equivalent HoCl6 octahedra, corners with four YCl6 octahedra, and faces with eight CsCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.80 Å) and two longer (2.82 Å) Na–Cl bond lengths. In the third Na1+ site, Na1+ is bonded to six Cl1- atoms to form NaCl6 octahedra that share corners with two equivalent HoCl6 octahedra, corners with four equivalent YCl6 octahedra, and faces with eight CsCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.80 Å) and two longer (2.82 Å) Na–Cl bond lengths. 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. There are two inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded to six Cl1- atoms to form YCl6 octahedra that share corners with six 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. In the second Y3+ site, Y3+ is bonded to six Cl1- atoms to form YCl6 octahedra that share corners with six 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 seven inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted linear geometry to four Cs1+, one Na1+, and one Y3+ atom. In the second Cl1- site, Cl1- is bonded in a distorted linear geometry to four Cs1+, one Na1+, and one Y3+ atom. In the third Cl1- site, Cl1- is bonded in a distorted linear geometry to four Cs1+, one Na1+, and one Ho3+ atom. In the fourth Cl1- site, Cl1- is bonded in a distorted linear geometry to four Cs1+, one Na1+, and one Y3+ atom. In the fifth Cl1- site, Cl1- is bonded in a distorted linear geometry to four Cs1+, one Na1+, and one Ho3+ atom. In the sixth Cl1- site, Cl1- is bonded in a distorted linear geometry to four Cs1+, one Na1+, and one Y3+ atom. In the seventh Cl1- site, Cl1- is bonded in a distorted linear geometry to four Cs1+, one Na1+, and one Y3+ atom.
