LiMnPO4 crystallizes in the cubic P2_13 space group. Li(1) is bonded to one O(2) and three equivalent O(1) atoms to form LiO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. Mn(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. P(1) is bonded to one O(2) and three equivalent O(1) atoms to form PO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to one Li(1), one Mn(1), and one P(1) atom. In the second O site, O(2) is bonded in a linear geometry to one Li(1) and one P(1) atom.
