The material structure described by Mn3Al2F15 crystallizes in the monoclinic P2_1/m space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one F(5), one F(6), one F(7), one F(9), and two equivalent F(4) atoms to form distorted MnF6 octahedra that share  a cornercorner with one Al(1)F6 octahedra, corners with three equivalent Al(2)F6 octahedra,  an edgeedge with one Mn(1)F6 octahedra, and  an edgeedge with one Mn(2)F6 octahedra. The corner-sharing octahedral tilt angles range from 9-65°. In the second Mn site, Mn(2) is bonded to two equivalent F(5), two equivalent F(6), and two equivalent F(8) atoms to form distorted MnF6 octahedra that share corners with four equivalent Al(1)F6 octahedra and edges with two equivalent Mn(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 9-61°. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded to one F(2), one F(3), two equivalent F(5), and two equivalent F(8) atoms to form AlF6 octahedra that share  a cornercorner with one Al(2)F6 octahedra, corners with two equivalent Mn(1)F6 octahedra, and corners with four equivalent Mn(2)F6 octahedra. The corner-sharing octahedral tilt angles range from 7-61°. In the second Al site, Al(2) is bonded to one F(1), one F(3), two equivalent F(4), and two equivalent F(7) atoms to form AlF6 octahedra that share  a cornercorner with one Al(1)F6 octahedra and corners with six equivalent Mn(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 7-65°. There are nine inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to one Al(2) atom. In the second F site, F(2) is bonded in a single-bond geometry to one Al(1) atom. In the third F site, F(3) is bonded in a linear geometry to one Al(1) and one Al(2) atom. In the fourth F site, F(4) is bonded in a distorted trigonal planar geometry to two equivalent Mn(1) and one Al(2) atom. In the fifth F site, F(5) is bonded in a 3-coordinate geometry to one Mn(1), one Mn(2), and one Al(1) atom. In the sixth F site, F(6) is bonded in a bent 120 degrees geometry to one Mn(1) and one Mn(2) atom. In the seventh F site, F(7) is bonded in a linear geometry to one Mn(1) and one Al(2) atom. In the eighth F site, F(8) is bonded in a linear geometry to one Mn(2) and one Al(1) atom. In the ninth F site, F(9) is bonded in a single-bond geometry to one Mn(1) atom. is represented by the CIF file [CIF]
