Materials Data on Sr(NO5)2 by Materials Project

Abstract

Sr(NO3)2(O2)2 crystallizes in the monoclinic C2/c space group. The structure is one-dimensional and consists of eight hydrogen peroxide molecules and two Sr(NO3)2 ribbons oriented in the (1, 0, 1) direction. In each Sr(NO3)2 ribbon, Sr is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Sr–O bond distances ranging from 2.57–2.73 Å. N is bonded in a trigonal planar geometry to three O atoms. There are a spread of N–O bond distances ranging from 1.23–1.32 Å. There are three inequivalent O sites. In the first O site, O is bonded in a distorted water-like geometry to one Sr and one N atom. In the second O site, O is bonded in a 1-coordinate geometry to two equivalent Sr and one N atom. In the third O site, O is bonded in a single-bond geometry to one N atom.
