The structure described by Li3Mn(PO4)2 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. In the second Li site, Li(2) is bonded to one O(1), one O(3), one O(4), and two equivalent O(2) atoms to form distorted LiO5 trigonal bipyramids that share corners with three equivalent Mn(1)O6 octahedra, corners with five equivalent P(1)O4 tetrahedra, and  an edgeedge with one Li(2)O5 trigonal bipyramid. The corner-sharing octahedral tilt angles range from 65-76°. Mn(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form MnO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra and corners with six equivalent Li(2)O5 trigonal bipyramids. P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share corners with three equivalent Mn(1)O6 octahedra and corners with five equivalent Li(2)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 51-54°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Li(1), one Li(2), one Mn(1), and one P(1) atom. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to one Li(1), two equivalent Li(2), and one P(1) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Li(2), one Mn(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Li(2), one Mn(1), and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
