Title: Materials Data on Sr2NF by Materials Project

Abstract

Sr2NF crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are seven inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to three N3- and three F1- atoms to form distorted SrN3F3 octahedra that share corners with five SrN3F3 octahedra, corners with two equivalent SrN3F2 trigonal bipyramids, edges with seven SrN3F3 octahedra, edges with two equivalent SrN3F2 trigonal bipyramids, and a faceface with one SrN3F3 octahedra. The corner-sharing octahedra tilt angles range from 1–15°. There are one shorter (2.56 Å) and two longer (2.62 Å) Sr–N bond lengths. There are one shorter (2.68 Å) and two longer (3.05 Å) Sr–F bond lengths. In the second Sr2+ site, Sr2+ is bonded to three N3- and two F1- atoms to form distorted SrN3F2 trigonal bipyramids that share corners with six SrN3F3 octahedra, corners with three equivalent SrN3F2 trigonal bipyramids, and edges with seven SrN3F3 octahedra. The corner-sharing octahedra tilt angles range from 2–82°. There are two shorter (2.54 Å) and one longer (2.59 Å) Sr–N bond lengths. There are one shorter (2.49 Å) and one longer (3.07 Å) Sr–F bond lengths. In the third Sr2+ site, Sr2+ is bonded to three N3- and three F1- atoms tomore » form SrN3F3 octahedra that share corners with six SrN3F3 octahedra, edges with ten SrN3F3 octahedra, and edges with two equivalent SrN3F2 trigonal bipyramids.
