Materials Data on LiVO2 by Materials Project

Abstract

LiVO2 is Caswellsilverite-like structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Li1+ is bonded to six equivalent O2- atoms to form LiO6 octahedra that share corners with six equivalent VO6 octahedra, edges with six equivalent LiO6 octahedra, and edges with six equivalent VO6 octahedra. The corner-sharing octahedral tilt angles are 4°. There are two shorter (2.13 Å) and four longer (2.17 Å) Li–O bond lengths. V3+ is bonded to six equivalent O2- atoms to form VO6 octahedra that share corners with six equivalent LiO6 octahedra, edges with six equivalent LiO6 octahedra, and edges with six equivalent VO6 octahedra. The corner-sharing octahedral tilt angles are 4°. There are two shorter (2.04 Å) and four longer (2.06 Å) V–O bond lengths. O2- is bonded to three equivalent Li1+ and three equivalent V3+ atoms to form a mixture of edge and corner-sharing OLi3V3 octahedra. The corner-sharing octahedral tilt angles are 0°.
