The crystal structure described by Ba2LiB5O10 crystallizes in the monoclinic P2_1/m space group. Li(1) is bonded to one O(2), one O(3), and two equivalent O(5) atoms to form LiO4 tetrahedra that share corners with four equivalent B(1)O4 tetrahedra. Ba(1) is bonded in a 8-coordinate geometry to one O(3), one O(5), one O(6), two equivalent O(1), and three equivalent O(4) atoms. There are three inequivalent B sites. In the first B site, B(1) is bonded to one O(1), one O(2), one O(5), and one O(6) atom to form BO4 tetrahedra that share  a cornercorner with one B(1)O4 tetrahedra and corners with two equivalent Li(1)O4 tetrahedra. In the second B site, B(2) is bonded in a trigonal planar geometry to one O(3) and two equivalent O(6) atoms. In the third B site, B(3) is bonded in a trigonal planar geometry to one O(1), one O(4), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(6) is bonded in a bent 120 degrees geometry to one Ba(1), one B(1), and one B(2) atom. In the second O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent Ba(1), one B(1), and one B(3) atom. In the third O site, O(2) is bonded in a distorted trigonal planar geometry to one Li(1) and two equivalent B(1) atoms. In the fourth O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Li(1), two equivalent Ba(1), and one B(2) atom. In the fifth O site, O(4) is bonded in a distorted single-bond geometry to three equivalent Ba(1) and one B(3) atom. In the sixth O site, O(5) is bonded in a distorted trigonal planar geometry to one Li(1), one Ba(1), one B(1), and one B(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
