Materials Data on Zn(N3O8)2 by Materials Project

Abstract

ZnO8N2(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 ZnO8 clusters. In each ZnO8 cluster, Zn2+ is bonded in a linear geometry to two equivalent O2- atoms. Both Zn–O bond lengths are 1.87 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one Zn2+ and one O2- atom. The O–O bond length is 1.32 Å. In the second O2- site, O2- is bonded in a distorted water-like geometry to two O2- atoms. There is one shorter (1.21 Å) and one longer (1.72 Å) O–O bond length. In the third O2- site, O2- is bonded in a distorted water-like geometry to two O2- atoms. In the fourth O2- site, O2- is bonded in a single-bond geometry to one O2- atom.
