Materials Data on LiMoO2 by Materials Project
LiMoO2 is Caswellsilverite-like 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 four equivalent MoO6 octahedra, corners with eight equivalent LiO6 octahedra, edges with two equivalent LiO6 octahedra, edges with four equivalent MoO6 octahedra, and faces with two equivalent MoO6 octahedra. The corner-sharing octahedra tilt angles range from 45–49°. There are a spread of Li–O bond distances ranging from 2.08–2.31 Å. Mo3+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with four equivalent LiO6 octahedra, corners with eight equivalent MoO6 octahedra, edges with two equivalent MoO6 octahedra, edges with four equivalent LiO6 octahedra, and faces with two equivalent LiO6 octahedra. The corner-sharing octahedra tilt angles range from 45–49°. There are three shorter (2.18 Å) and three longer (2.19 Å) Mo–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to three equivalent Li1+ and three equivalent Mo3+ atoms. In the second O2- site, O2- is bonded in a 6-coordinate geometry to three equivalent Li1+ and three equivalent Mo3+ atoms.
