SrMnOF5 crystallizes in the monoclinic P2_1/m space group. Sr(1) is bonded in a 9-coordinate geometry to two equivalent O(1), one F(1), two equivalent F(2), and four equivalent F(3) atoms. Mn(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form corner-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles are 40°. O(1) is bonded in a bent 150 degrees geometry to two equivalent Sr(1) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal non-coplanar geometry to one Sr(1) and two equivalent Mn(1) atoms. In the second F site, F(2) is bonded in a bent 150 degrees geometry to one Sr(1) and one Mn(1) atom. In the third F site, F(3) is bonded in a 3-coordinate geometry to two equivalent Sr(1) and one Mn(1) atom.
