Materials Data on Mn(N3O8)2 by Materials Project
Mn(NO6)2N2(NO2)2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of four ammonia molecules; four nitrous acid molecules; and one Mn(NO6)2 sheet oriented in the (1, 0, 0) direction. In the Mn(NO6)2 sheet, Mn2+ is bonded in a distorted octahedral geometry to six O2- atoms. There are a spread of Mn–O bond distances ranging from 1.69–2.10 Å. N5+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both N–O bond lengths are 1.26 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one N5+ and one O2- atom. The O–O bond length is 2.39 Å. In the second O2- site, O2- is bonded in a single-bond geometry to one N5+ and one O2- atom. The O–O bond length is 3.02 Å. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Mn2+ and two O2- atoms. There is one shorter (1.29 Å) and one longer (2.38 Å) O–O bond length. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Mn2+ and three O2- atoms. There are one shorter (2.51 Å) and one longer (2.62 Å) O–O bond lengths. In the fifth O2- site, O2- is bonded in a single-bond geometry to one Mn2+ and one O2- atom. The O–O bond length is 3.04 Å. In the sixth O2- site, O2- is bonded in a 6-coordinate geometry to six O2- atoms.
