Materials Data on Li3V2(GeO4)3 by Materials Project

Abstract

Li3V2(GeO4)3 crystallizes in the cubic Ia-3d space group. The structure is three-dimensional. Li1+ is bonded in a distorted body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.33 Å) and four longer (2.50 Å) Li–O bond lengths. V+4.50+ is bonded to six equivalent O2- atoms to form VO6 octahedra that share corners with six equivalent GeO4 tetrahedra. All V–O bond lengths are 1.92 Å. Ge4+ is bonded to four equivalent O2- atoms to form GeO4 tetrahedra that share corners with four equivalent VO6 octahedra. The corner-sharing octahedral tilt angles are 47°. All Ge–O bond lengths are 1.77 Å. O2- is bonded in a 4-coordinate geometry to two equivalent Li1+, one V+4.50+, and one Ge4+ atom.
