LaBGeO5 crystallizes in the trigonal P3_1 space group. La(1) is bonded in a 9-coordinate geometry to one O(2), two equivalent O(1), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. B(1) is bonded to one O(3), one O(4), and two equivalent O(2) atoms to form BO4 tetrahedra that share corners with two equivalent B(1)O4 tetrahedra and corners with two equivalent Ge(1)O4 tetrahedra. Ge(1) is bonded to one O(1), one O(3), one O(4), and one O(5) atom to form GeO4 tetrahedra that share corners with two equivalent B(1)O4 tetrahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent La(1) and one Ge(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one La(1) and two equivalent B(1) atoms. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to two equivalent La(1), one B(1), and one Ge(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to two equivalent La(1), one B(1), and one Ge(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to two equivalent La(1) and one Ge(1) atom.
