Materials Data on LiLa2ReO6 by Materials Project
LiLa2ReO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six equivalent ReO6 octahedra. The corner-sharing octahedra tilt angles range from 29–30°. There are a spread of Li–O bond distances ranging from 2.12–2.17 Å. La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.40–2.83 Å. Re5+ is bonded to six O2- atoms to form ReO6 octahedra that share corners with six equivalent LiO6 octahedra. The corner-sharing octahedra tilt angles range from 29–30°. There is four shorter (1.98 Å) and two longer (2.00 Å) Re–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to one Li1+, three equivalent La3+, and one Re5+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to one Li1+, three equivalent La3+, and one Re5+ atom. In the third O2- site, O2- is bonded to one Li1+, two equivalent La3+, and one Re5+ atom to form distorted corner-sharing OLiLa2Re tetrahedra.
