Materials Data on Li2V2SiGeO10 by Materials Project
Abstract
Li2V2GeSiO10 crystallizes in the orthorhombic C222 space group. The structure is three-dimensional. Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with two equivalent LiO6 octahedra, corners with two equivalent GeO4 tetrahedra, corners with two equivalent SiO4 tetrahedra, corners with two equivalent VO5 trigonal bipyramids, and edges with two equivalent VO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 56°. There are a spread of Li–O bond distances ranging from 2.05–2.56 Å. V5+ is bonded to five O2- atoms to form distorted VO5 trigonal bipyramids that share corners with two equivalent LiO6 octahedra, corners with two equivalent GeO4 tetrahedra, corners with two equivalent SiO4 tetrahedra, and edges with two equivalent LiO6 octahedra. The corner-sharing octahedral tilt angles are 62°. There are a spread of V–O bond distances ranging from 1.63–1.92 Å. Ge4+ is bonded to four equivalent O2- atoms to form GeO4 tetrahedra that share corners with four equivalent LiO6 octahedra and corners with four equivalent VO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 60°. All Ge–O bond lengths are 1.77 Å. Si4+ is bonded to four equivalent O2- atoms to form SiO4 tetrahedra that share corners with four equivalent LiO6 octahedra andmore »

In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Li1+ and one V5+ atom.
