Materials Data on Na3CeCl6 by Materials Project
(Na)2NaCeCl6 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 NaCeCl6 framework. In the NaCeCl6 framework, Na1+ is bonded to six equivalent Cl1- atoms to form NaCl6 octahedra that share corners with six equivalent CeCl6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Na–Cl bond lengths are 2.71 Å. Ce3+ is bonded to six equivalent Cl1- atoms to form CeCl6 octahedra that share corners with six equivalent NaCl6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Ce–Cl bond lengths are 2.73 Å. Cl1- is bonded in a linear geometry to one Na1+ and one Ce3+ atom.
