description: (MnFeH12O6F5)2(H2)2O2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional and consists of eight hydrogen molecules, eight water molecules, and one MnFeH12O6F5 framework. In the MnFeH12O6F5 framework, there are two inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Mn–O bond distances ranging from 2.12–2.31 Å. In the second Mn2+ site, Mn2+ is bonded in a distorted see-saw-like geometry to four O2- atoms. There are two shorter (2.09 Å) and two longer (2.17 Å) Mn–O bond lengths. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded in an octahedral geometry to two equivalent O2- and four F1- atoms. Both Fe–O bond lengths are 2.09 Å. There is two shorter (1.95 Å) and two longer (1.96 Å) Fe–F bond length. In the second Fe3+ site, Fe3+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of Fe–F bond distances ranging from 1.92–2.04 Å. There are twelve inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom.
