The compound described by LiMn2(PO4)2 crystallizes in the monoclinic C2 space group. Li(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form distorted LiO4 tetrahedra that share corners with two equivalent Mn(2)O4 tetrahedra and corners with four equivalent P(1)O4 tetrahedra. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a distorted see-saw-like geometry to two equivalent O(2) and two equivalent O(4) atoms. In the second Mn site, Mn(2) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form MnO4 tetrahedra that share corners with two equivalent Li(1)O4 tetrahedra and 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 two equivalent Li(1)O4 tetrahedra and corners with two equivalent Mn(2)O4 tetrahedra. 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(2), and one P(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Li(1), one Mn(1), and one P(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Mn(2) and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Mn(1) and one P(1) atom. is represented by the CIF file [CIF]
