The structure described by LiMnF3 is Ilmenite-like structured and crystallizes in the orthorhombic Pnna space group. Li(1) is bonded in a 6-coordinate geometry to two equivalent F(2) and four equivalent F(1) atoms. Mn(1) is bonded to two equivalent F(2) and four equivalent F(1) atoms to form a mixture of corner and edge-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles are 61°. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 4-coordinate geometry to two equivalent Li(1) and two equivalent Mn(1) atoms. In the second F site, F(2) is bonded to two equivalent Li(1) and two equivalent Mn(1) atoms to form distorted corner-sharing FLi2Mn2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
