Materials Data on LiLa4MnO8 by Materials Project
LiLa4MnO8 is (La,Ba)CuO4-derived structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with four equivalent MnO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (1.94 Å) and two longer (2.35 Å) Li–O bond lengths. There are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 1-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.30–2.77 Å. In the second La3+ site, La3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.36–2.78 Å. Mn3+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with four equivalent LiO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (1.90 Å) and two longer (2.33 Å) Mn–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to five La3+ and one Mn3+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry to one Li1+, four La3+, and one Mn3+ atom. In the third O2- site, O2- is bonded in a 6-coordinate geometry to one Li1+ and five La3+ atoms.
