Materials Data on LiGeBO4 by Materials Project

Abstract

LiBGeO4 is Chalcostibite-derived structured and crystallizes in the orthorhombic Fmm2 space group. The structure is three-dimensional. Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are two shorter (1.95 Å) and two longer (2.13 Å) Li–O bond lengths. B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share corners with four equivalent GeO4 tetrahedra. There is two shorter (1.48 Å) and two longer (1.54 Å) B–O bond length. Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with four equivalent BO4 tetrahedra. There is two shorter (1.78 Å) and two longer (1.80 Å) Ge–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one B3+, and one Ge4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one B3+, and one Ge4+ atom.
