description: MnOF is zeta iron carbide-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are eight inequivalent Mn3+ sites. In the first Mn3+ site, Mn3+ is bonded to three O2- and three F1- atoms to form MnO3F3 octahedra that share corners with eight MnO3F3 octahedra and edges with two MnO2F4 octahedra. The corner-sharing octahedra tilt angles range from 46–56°. There are a spread of Mn–O bond distances ranging from 1.96–2.03 Å. There are a spread of Mn–F bond distances ranging from 1.99–2.19 Å. In the second Mn3+ site, Mn3+ is bonded to two O2- and four F1- atoms to form a mixture of edge and corner-sharing MnO2F4 octahedra. The corner-sharing octahedra tilt angles range from 50–59°. There is one shorter (1.91 Å) and one longer (1.97 Å) Mn–O bond length. There are a spread of Mn–F bond distances ranging from 2.03–2.13 Å. In the third Mn3+ site, Mn3+ is bonded to three O2- and three F1- atoms to form a mixture of edge and corner-sharing MnO3F3 octahedra. The corner-sharing octahedra tilt angles range from 47–59°. There are a spread of Mn–O bond distances ranging from 1.94–1.97 Å. There are one shorter (2.02 Å) and two longer (2.22 Å) Mn–F bond lengths.

There is two shorter (1.87 Å) and one longer (1.91 Å) Mn–O bond length. There are two shorter (1.98 Å) and one longer (2.04 Å) Mn–F bond lengths. In the sixth Mn3+ site, Mn3+ is bonded to three O2- and three F1- atoms to form a mixture of distorted edge and corner-sharing MnO3F3 octahedra. The corner-sharing octahedra tilt angles range from 45–59°. There are one shorter (1.98 Å) and two longer (2.03 Å) Mn–O bond lengths. There are a spread of Mn–F bond distances ranging from 2.13–2.33 Å. In the seventh Mn3+ site, Mn3+ 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 41–58°. There are a spread of Mn–O bond distances ranging from 1.94–2.06 Å. There are one shorter (2.17 Å) and one longer (2.24 Å) Mn–F bond lengths. In the eighth Mn3+ site, Mn3+ is bonded to three O2- and three F1- atoms to form MnO3F3 octahedra that share corners with eight MnO3F3 octahedra and edges with two MnO2F4 octahedra. The corner-sharing octahedra tilt angles range from 47–58°. There are a spread of Mn–O bond distances ranging from 1.91–1.98 Å. There are a spread of Mn–F bond distances ranging from 2.05–2.31 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to three Mn3+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to three Mn3+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to three Mn3+ atoms.
