The structure described by Mn7F18 crystallizes in the triclinic P-1 space group. There are four inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one F(1), one F(2), one F(4), one F(5), one F(7), and one F(9) atom to form a mixture of corner and edge-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles range from 37-50°. In the second Mn site, Mn(2) is bonded to two equivalent F(3), two equivalent F(4), and two equivalent F(7) atoms to form a mixture of corner and edge-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles range from 38-54°. In the third Mn site, Mn(3) is bonded to one F(1), one F(2), one F(3), one F(6), one F(8), and one F(9) atom to form a mixture of corner and edge-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles range from 37-50°. In the fourth Mn site, Mn(4) is bonded to one F(4), one F(5), one F(8), one F(9), and two equivalent F(6) atoms to form a mixture of distorted corner and edge-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles range from 43-54°. There are nine inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to one Mn(1) and one Mn(3) atom. In the second F site, F(2) is bonded in a bent 150 degrees geometry to one Mn(1) and one Mn(3) atom. In the third F site, F(3) is bonded in a bent 150 degrees geometry to one Mn(2) and one Mn(3) atom. In the fourth F site, F(4) is bonded in a distorted trigonal planar geometry to one Mn(1), one Mn(2), and one Mn(4) atom. In the fifth F site, F(5) is bonded in a bent 150 degrees geometry to one Mn(1) and one Mn(4) atom. In the sixth F site, F(6) is bonded in a trigonal non-coplanar geometry to one Mn(3) and two equivalent Mn(4) atoms. In the seventh F site, F(7) is bonded in a water-like geometry to one Mn(1) and one Mn(2) atom. In the eighth F site, F(8) is bonded in a water-like geometry to one Mn(3) and one Mn(4) atom. In the ninth F site, F(9) is bonded in a distorted trigonal planar geometry to one Mn(1), one Mn(3), and one Mn(4) atom. is represented by the CIF file [CIF]
