The material structure described by LiMnPO4 crystallizes in the monoclinic Cc space group. Li(1) is bonded in a distorted see-saw-like geometry to one O(1), one O(2), one O(3), and one O(4) atom. Mn(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form distorted MnO4 trigonal pyramids that share corners with four equivalent P(1)O4 tetrahedra. 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 four equivalent Mn(1)O4 trigonal pyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Li(1), one Mn(1), and one P(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Li(1), one Mn(1), and one P(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Li(1), one Mn(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Li(1), one Mn(1), and one P(1) atom. is represented by the CIF file [CIF]
