Materials Data on Na2EuCuCl6 by Materials Project
(Na)2EuCuCl6 is High-temperature superconductor-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of eight sodium molecules and one EuCuCl6 framework. In the EuCuCl6 framework, Eu3+ is bonded to six equivalent Cl1- atoms to form EuCl6 octahedra that share corners with six equivalent CuCl6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Eu–Cl bond lengths are 2.72 Å. Cu1+ is bonded to six equivalent Cl1- atoms to form CuCl6 octahedra that share corners with six equivalent EuCl6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Cu–Cl bond lengths are 2.46 Å. Cl1- is bonded in a linear geometry to one Eu3+ and one Cu1+ atom.
