Materials Data on Li4Ga3Si3BrO12 by Materials Project

Abstract

Li4Ga3Si3O12Br crystallizes in the cubic P-43n space group. The structure is three-dimensional. Li1+ is bonded to three equivalent O2- and one Br1- atom to form LiBrO3 tetrahedra that share corners with three equivalent LiBrO3 tetrahedra, corners with three equivalent GaO4 tetrahedra, and corners with three equivalent SiO4 tetrahedra. All Li–O bond lengths are 2.02 Å. The Li–Br bond length is 2.69 Å. Ga3+ is bonded to four equivalent O2- atoms to form GaO4 tetrahedra that share corners with four equivalent LiBrO3 tetrahedra and corners with four equivalent SiO4 tetrahedra. All Ga–O bond lengths are 1.85 Å. Si4+ is bonded to four equivalent O2- atoms to form SiO4 tetrahedra that share corners with four equivalent LiBrO3 tetrahedra and corners with four equivalent GaO4 tetrahedra. All Si–O bond lengths are 1.65 Å. O2- is bonded in a trigonal planar geometry to one Li1+, one Ga3+, and one Si4+ atom. Br1- is bonded in a tetrahedral geometry to four equivalent Li1+ atoms.
