Materials Data on LaGeBO5 by Materials Project
LaBGeO5 crystallizes in the trigonal P3_1 space group. The structure is three-dimensional. La3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.41–2.76 Å. B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share corners with two equivalent BO4 tetrahedra and corners with two equivalent GeO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.46–1.52 Å. Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with two equivalent BO4 tetrahedra. There is two shorter (1.74 Å) and two longer (1.80 Å) Ge–O bond length. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent La3+ and one Ge4+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one La3+ and two equivalent B3+ atoms. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent La3+, one B3+, and one Ge4+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent La3+, one B3+, and one Ge4+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent La3+ and one Ge4+ atom.
