Materials Data on Mn(N3O8)2 by Materials Project

Abstract

MnO8N2(NO2)4 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four ammonia molecules; eight hydroxylamine, n-hydroxy- molecules; and two MnO8 clusters. In each MnO8 cluster, Mn2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Mn–O bond distances ranging from 1.97–2.39 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Mn2+ and one O2- atom. The O–O bond length is 1.33 Å. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Mn2+ and one O2- atom. The O–O bond length is 1.23 Å. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Mn2+ and one O2- atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one O2- atom.
