Materials Data on Li2Ge7O15 by Materials Project
Li2Ge7O15 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with ten GeO4 tetrahedra and an edgeedge with one GeO6 octahedra. There are a spread of Li–O bond distances ranging from 2.02–2.38 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with eight GeO4 tetrahedra and edges with two equivalent GeO6 octahedra. There are a spread of Li–O bond distances ranging from 1.98–2.34 Å. There are four inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to six O2- atoms to form GeO6 octahedra that share corners with six GeO4 tetrahedra and edges with three LiO6 octahedra. There is four shorter (1.91 Å) and two longer (1.92 Å) Ge–O bond length. In the second Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share a cornercorner with one GeO6 octahedra, corners with three LiO6 octahedra, and corners with three GeO4 tetrahedra. The corner-sharing octahedra tilt angles range from 48–65°. There are a spread of Ge–O bond distances ranging from 1.74–1.80 Å. In the third Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share a cornercorner with one GeO6 octahedra, corners with three LiO6 octahedra, and corners with three GeO4 tetrahedra. The corner-sharing octahedra tilt angles range from 46–67°. There are a spread of Ge–O bond distances ranging from 1.75–1.79 Å. In the fourth Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share a cornercorner with one GeO6 octahedra, corners with three LiO6 octahedra, and corners with three GeO4 tetrahedra. The corner-sharing octahedra tilt angles range from 47–68°. There are a spread of Ge–O bond distances ranging from 1.74–1.81 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two Ge4+ atoms. In the second O2- site, O2- is bonded in a trigonal planar geometry to one Li1+ and two Ge4+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two Ge4+ atoms. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to one Li1+ and two Ge4+ atoms. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Ge4+ atoms. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Ge4+ atoms. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two Ge4+ atoms. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two Ge4+ atoms.
