BaMnOF5 crystallizes in the monoclinic P2_1/m space group. Ba(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 32°. O(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Ba(1) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a 3-coordinate geometry to one Ba(1) and two equivalent Mn(1) atoms. In the second F site, F(2) is bonded in a bent 150 degrees geometry to one Ba(1) and one Mn(1) atom. In the third F site, F(3) is bonded in a 3-coordinate geometry to two equivalent Ba(1) and one Mn(1) atom.
