The crystal structure described by Li3Mn(BO3)2 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent Li sites. In the first Li site, Li(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(2), one O(3), and one O(5) atom. In the second Li site, Li(2) is bonded to one O(1), one O(2), one O(3), and one O(6) atom to form distorted LiO4 tetrahedra that share corners with two equivalent Mn(1)O6 octahedra,  an edgeedge with one Mn(1)O6 octahedra, and  an edgeedge with one Li(3)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 31-74°. In the third Li site, Li(3) is bonded to one O(3), one O(4), one O(5), and one O(6) atom to form distorted LiO4 tetrahedra that share corners with two equivalent Mn(1)O6 octahedra,  an edgeedge with one Mn(1)O6 octahedra, and  an edgeedge with one Li(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 61-85°.

There are two inequivalent B sites. In the first B site, B(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. In the second B site, B(2) is bonded in a trigonal planar geometry to one O(4), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(6) is bonded in a distorted rectangular see-saw-like geometry to one Li(2), one Li(3), one Mn(1), and one B(2) atom. In the second O site, O(1) is bonded in a 4-coordinate geometry to one Li(1), one Li(2), one Mn(1), and one B(1) atom. In the third O site, O(2) is bonded in a distorted see-saw-like geometry to one Li(1), one Li(2), one Mn(1), and one B(1) atom.
