The structure described by Li3Mn(PO4)2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form LiO6 octahedra that share corners with six equivalent Li(2)O4 tetrahedra, corners with six equivalent P(1)O4 tetrahedra, and edges with two equivalent Mn(1)O6 octahedra. In the second Li site, Li(2) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form distorted LiO4 tetrahedra that share corners with three equivalent Li(1)O6 octahedra, corners with three equivalent Mn(1)O6 octahedra, corners with two equivalent P(1)O4 tetrahedra, and  an edgeedge with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 66-79°. Mn(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form MnO6 octahedra that share corners with six equivalent Li(2)O4 tetrahedra, corners with six equivalent P(1)O4 tetrahedra, and edges with two equivalent Li(1)O6 octahedra. P(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form PO4 tetrahedra that share corners with three equivalent Li(1)O6 octahedra, corners with three equivalent Mn(1)O6 octahedra, corners with two equivalent Li(2)O4 tetrahedra, and  an edgeedge with one Li(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 48-54°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Li(1), one Li(2), and one P(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Li(2), one Mn(1), and one P(1) atom. In the third O site, O(3) is bonded to one Li(1), one Li(2), one Mn(1), and one P(1) atom to form a mixture of distorted corner and edge-sharing OLi2MnP trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
