The structure described by Li4B2O5 crystallizes in the monoclinic C2/c space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. In the second Li site, Li(2) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form a mixture of distorted edge and corner-sharing LiO4 tetrahedra. B(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to two equivalent Li(1), two equivalent Li(2), and one B(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to two equivalent Li(1), two equivalent Li(2), and one B(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Li(1) and two equivalent B(1) atoms. is represented by the CIF card [CIF]
