Materials Data on Cs2KEuCl6 by Materials Project
Cs2KEuCl6 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 KCl6 octahedra, and faces with four equivalent EuCl6 octahedra. All Cs–Cl bond lengths are 4.06 Å. K1+ is bonded to six equivalent Cl1- atoms to form KCl6 octahedra that share corners with six equivalent EuCl6 octahedra and faces with eight equivalent CsCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All K–Cl bond lengths are 3.02 Å. Eu3+ is bonded to six equivalent Cl1- atoms to form EuCl6 octahedra that share corners with six equivalent KCl6 octahedra and faces with eight equivalent CsCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Eu–Cl bond lengths are 2.71 Å. Cl1- is bonded in a distorted linear geometry to four equivalent Cs1+, one K1+, and one Eu3+ atom.
