Materials Data on Cs2DyCuCl6 by Materials Project

Abstract

Cs2DyCuCl6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Cs1+ is bonded to twelve equivalent Cl1- atoms to form CsCl12 cuboctahedra that share corners with twelve equivalent CsCl12 cuboctahedra, faces with six equivalent CsCl12 cuboctahedra, faces with four equivalent DyCl6 octahedra, and faces with four equivalent CuCl6 octahedra. All Cs–Cl bond lengths are 3.72 Å. Dy3+ is bonded to six equivalent Cl1- atoms to form DyCl6 octahedra that share corners with six equivalent CuCl6 octahedra and faces with eight equivalent CsCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Dy–Cl bond lengths are 2.65 Å. Cu1+ is bonded to six equivalent Cl1- atoms to form CuCl6 octahedra that share corners with six equivalent DyCl6 octahedra and faces with eight equivalent CsCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Cu–Cl bond lengths are 2.61 Å. Cl1- is bonded in a distorted linear geometry to four equivalent Cs1+, one Dy3+, and one Cu1+ atom.
