Materials Data on Sr(NO3)2 by Materials Project

Sr(NO3)2 crystallizes in the cubic Pa-3 space group. The structure is three-dimensional. Sr2+ is bonded to twelve equivalent O2- atoms to form corner-sharing SrO12 cuboctahedra. There are six shorter (2.75 Å) and six longer (2.90 Å) Sr–O bond lengths. N5+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All N–O bond lengths are 1.27 Å. O2- is bonded in a distorted single-bond geometry to two equivalent Sr2+ and one N5+ atom.

Materials Data on Sr2NO6 by Materials Project

Sr2NO6 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Sr is bonded in a 9-coordinate geometry to nine O atoms. There are six shorter (2.64 Å) and three longer (2.75 Å) Sr–O bond lengths. N is bonded in a trigonal planar geometry to three equivalent O atoms. All N–O bond lengths are 1.27 Å. There are two inequivalent O sites. In the first O site, O is bonded in a distorted single-bond geometry to two equivalent Sr and one N atom. In the second O site, O is bonded in a rectangular see-saw-like geometry to four equivalent Sr atoms.

Materials Data on Sr(NO5)2 by Materials Project

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.
