The structure described by LiMnPO4 crystallizes in the orthorhombic Pnma space group. Li(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form LiO6 octahedra that share corners with six equivalent Mn(1)O4 tetrahedra, corners with six equivalent P(1)O4 tetrahedra, and edges with two equivalent Li(1)O6 octahedra. Mn(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form distorted MnO4 tetrahedra that share corners with six equivalent Li(1)O6 octahedra and corners with four equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 75-78°. 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 six equivalent Li(1)O6 octahedra and corners with four equivalent Mn(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 44-54°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1), one Mn(1), and one P(1) atom to form a mixture of distorted edge and corner-sharing OLi2MnP tetrahedra. In the second O site, O(2) is bonded to two equivalent Li(1), one Mn(1), and one P(1) atom to form a mixture of distorted edge and corner-sharing OLi2MnP tetrahedra. 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. is represented by the CIF card [CIF]
