Mn8O13F3 is zeta iron carbide-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are eight inequivalent Mn+3.62+ sites. In the first Mn+3.62+ site, Mn+3.62+ is bonded to four O2- and two F1- atoms to form a mixture of edge and corner-sharing MnO4F2 octahedra. The corner-sharing octahedra tilt angles range from 43–59°. There are a spread of Mn–O bond distances ranging from 1.91–1.99 Å. There are one shorter (2.06 Å) and one longer (2.12 Å) Mn–F bond lengths. In the second Mn+3.62+ site, Mn+3.62+ is bonded to five O2- and one F1- atom to form MnO5F octahedra that share corners with eight MnO6 octahedra and edges with two MnO4F2 octahedra. The corner-sharing octahedra tilt angles range from 44–54°. There are a spread of Mn–O bond distances ranging from 1.86–2.06 Å. The Mn–F bond length is 1.93 Å. In the third Mn+3.62+ site, Mn+3.62+ is bonded to five O2- and one F1- atom to form a mixture of edge and corner-sharing MnO5F octahedra. The corner-sharing octahedra tilt angles range from 48–57°. There are a spread of Mn–O bond distances ranging from 1.93–1.99 Å. The Mn–F bond length is 2.20 Å. In the fourth Mn+3.62+ site, Mn+3.62+ is bonded to five O2- and one F1- atom to form MnO5F octahedra that share corners with eight MnO5F octahedra and edges with two MnO4F2 octahedra.
