Title: Materials Data on La2Ge2O7 by Materials Project

Abstract

La2Ge2O7 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of La–O bond distances ranging from 2.46–2.78 Å. In the second La3+ site, La3+ is bonded in a 6-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.36–3.00 Å. In the third La3+ site, La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.37–2.72 Å. In the fourth La3+ site, La3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.44–2.99 Å. There are four inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. There are a spread of Ge–O bond distances ranging from 1.75–1.84 Å. In the second Ge4+ site, Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. There are a spread of Ge–O bond distances ranging from 1.73–1.81 Å. In the third Ge4+ site, Ge4+more » is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. There are a spread of Ge–O bond distances ranging from 1.75–1.85 Å. In the fourth Ge4+ site, Ge4+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Ge–O bond distances ranging from 1.76–1.81 Å. There are fourteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two La3+ and one Ge4+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to three La3+ and one Ge4+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to three La3+ and one Ge4+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one La3+ and two Ge4+ atoms. In the fifth O2- site, O2- is bonded in a distorted tetrahedral geometry to three La3+ and one Ge4+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two La3+ and one Ge4+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to two La3+ and one Ge4+ atom. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to one La3+ and two Ge4+ atoms. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to two La3+ and one Ge4+ atom. In the tenth O2- site, O2- is bonded in a 3-coordinate geometry to two La3+ and one Ge4+ atom. In the eleventh O2- site, O2- is bonded in a 4-coordinate geometry to three La3+ and one Ge4+ atom. In the twelfth O2- site, O2- is bonded in a 1-coordinate geometry to three La3+ and one Ge4+ atom. In the thirteenth O2- site, O2- is bonded in a 4-coordinate geometry to three La3+ and one Ge4+ atom. In the fourteenth O2- site, O2- is bonded in a distorted trigonal planar geometry to two La3+ and one Ge4+ atom.« less
