Materials Data on Na2LiRuF6 by Materials Project

Abstract

Na2LiRuF6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Na1+ is bonded to twelve equivalent F1- atoms to form NaF12 cuboctahedra that share corners with twelve equivalent NaF12 cuboctahedra, faces with six equivalent NaF12 cuboctahedra, faces with four equivalent LiF6 octahedra, and faces with four equivalent RuF6 octahedra. All Na–F bond lengths are 2.82 Å. Li1+ is bonded to six equivalent F1- atoms to form LiF6 octahedra that share corners with six equivalent RuF6 octahedra and faces with eight equivalent NaF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Li–F bond lengths are 1.98 Å. Ru3+ is bonded to six equivalent F1- atoms to form RuF6 octahedra that share corners with six equivalent LiF6 octahedra and faces with eight equivalent NaF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ru–F bond lengths are 2.01 Å. F1- is bonded in a distorted linear geometry to four equivalent Na1+, one Li1+, and one Ru3+ atom.
