Materials Data on LiCa3OsO6 by Materials Project
LiCa3OsO6 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Li1+ is bonded to six equivalent O2- atoms to form distorted LiO6 pentagonal pyramids that share faces with two equivalent OsO6 octahedra. All Li–O bond lengths are 2.24 Å. Ca2+ is bonded in a 8-coordinate geometry to eight equivalent O2- atoms. There are a spread of Ca–O bond distances ranging from 2.34–2.75 Å. Os5+ is bonded to six equivalent O2- atoms to form OsO6 octahedra that share faces with two equivalent LiO6 pentagonal pyramids. All Os–O bond lengths are 1.99 Å. O2- is bonded in a 6-coordinate geometry to one Li1+, four equivalent Ca2+, and one Os5+ atom.
