LiMn(PO3)3 crystallizes in the trigonal R3 space group. Li(1) is bonded in a distorted T-shaped geometry to three equivalent O(2) atoms. Mn(1) is bonded to three equivalent O(2) and three equivalent O(3) atoms to form distorted MnO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form PO4 tetrahedra that share corners with two equivalent Mn(1)O6 octahedra and corners with two equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 51-56°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent P(1) atoms. 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 bent 120 degrees geometry to one Mn(1) and one P(1) atom.
