Materials Data on Na3SmCl6 by Materials Project

(Na)2NaSmCl6 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 NaSmCl6 framework. In the NaSmCl6 framework, Na1+ is bonded to six equivalent Cl1- atoms to form NaCl6 octahedra that share corners with six equivalent SmCl6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Na–Cl bond lengths are 2.70 Å. Sm3+ is bonded to six equivalent Cl1- atoms to form SmCl6 octahedra that share corners with six equivalent NaCl6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Sm–Cl bond lengths are 2.68 Å. Cl1- is bonded in a linear geometry to one Na1+ and one Sm3+ atom.
