Materials Data on K3EuCl6 by Materials Project
(K)2KEuCl6 is High-temperature superconductor-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of eight potassium molecules and one KEuCl6 framework. In the KEuCl6 framework, K1+ is bonded to six equivalent Cl1- atoms to form KCl6 octahedra that share corners with six equivalent EuCl6 octahedra. The corner-sharing octahedral tilt angles are 0°. All K–Cl bond lengths are 2.98 Å. Eu3+ is bonded to six equivalent Cl1- atoms to form EuCl6 octahedra that share corners with six equivalent KCl6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Eu–Cl bond lengths are 2.70 Å. Cl1- is bonded in a linear geometry to one K1+ and one Eu3+ atom.
