Abstract
MnO2 crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. there are twelve inequivalent Mn4+ sites. In the first Mn4+ site, Mn4+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with three MnO4 tetrahedra and edges with four equivalent MnO6 octahedra. There are a spread of Mn–O bond distances ranging from 1.87–2.00 Å. In the second Mn4+ site, Mn4+ is bonded to six O2- atoms to form MnO6 octahedra that share a cornercorner with one MnO4 tetrahedra and edges with five MnO6 octahedra. There are a spread of Mn–O bond distances ranging from 1.87–2.02 Å. In the third Mn4+ site, Mn4+ is bonded to six O2- atoms to form edge-sharing MnO6 octahedra. All Mn–O bond lengths are 1.95 Å. In the fourth Mn4+ site, Mn4+ is bonded to four O2- atoms to form corner-sharing MnO4 tetrahedra. The corner-sharing octahedral tilt angles are 59°. There is three shorter (1.91 Å) and one longer (2.02 Å) Mn–O bond length. In the fifth Mn4+ site, Mn4+ is bonded to six O2- atoms to form edge-sharing MnO6 octahedra. There is three shorter (1.94 Å) and three longer (1.96 Å) Mn–O bond length. In the sixth Mn4+ site,more »
