Materials Data on MnNO5 by Materials Project
MnO5N crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of four MnO5N ribbons oriented in the (0, 1, 0) direction. Mn7+ is bonded to six O2- atoms to form edge-sharing MnO6 octahedra. There are a spread of Mn–O bond distances ranging from 1.88–2.06 Å. N3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.23–1.30 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three equivalent Mn7+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to two equivalent Mn7+ atoms. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Mn7+ and one N3+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one N3+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one N3+ atom.
