The material structure described by LiMnF3 is Ilmenite-like structured and crystallizes in the orthorhombic Pnma space group. Li(1) is bonded to one F(2), one F(3), two equivalent F(1), and two equivalent F(4) atoms to form LiF6 octahedra that share corners with four equivalent Li(1)F6 octahedra, corners with two equivalent Mn(2)F6 pentagonal pyramids,  an edgeedge with one Li(1)F6 octahedra, and edges with two equivalent Mn(2)F6 pentagonal pyramids. The corner-sharing octahedral tilt angles range from 39-56°. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 6-coordinate geometry to one F(2), one F(3), two equivalent F(1), and two equivalent F(4) atoms. In the second Mn site, Mn(2) is bonded to one F(2), one F(3), two equivalent F(1), and two equivalent F(4) atoms to form distorted MnF6 pentagonal pyramids that share corners with four equivalent Li(1)F6 octahedra and edges with four equivalent Li(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 65-77°. There are four inequivalent F sites. In the first F site, F(1) is bonded to two equivalent Li(1), one Mn(1), and one Mn(2) atom to form a mixture of distorted corner and edge-sharing FLi2Mn2 trigonal pyramids. In the second F site, F(2) is bonded to two equivalent Li(1), one Mn(1), and one Mn(2) atom to form a mixture of corner and edge-sharing FLi2Mn2 tetrahedra. In the third F site, F(3) is bonded to two equivalent Li(1), one Mn(1), and one Mn(2) atom to form a mixture of distorted corner and edge-sharing FLi2Mn2 trigonal pyramids. In the fourth F site, F(4) is bonded in a 4-coordinate geometry to two equivalent Li(1), one Mn(1), and one Mn(2) atom. is represented by the CIF file [CIF]
