Title: Materials Data on BaSrI4 by Materials Project

Abstract

BaSrI4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ba2+ is bonded to seven I1- atoms to form distorted BaI7 pentagonal bipyramids that share corners with four equivalent BaI7 pentagonal bipyramids, an edgeedge with one BaI7 pentagonal bipyramid, and edges with four equivalent SrI5 trigonal bipyramids. There are a spread of Ba–I bond distances ranging from 3.54–3.75 Å. Sr2+ is bonded to five I1- atoms to form SrI5 trigonal bipyramids that share edges with four equivalent BaI7 pentagonal bipyramids and an edgeedge with one SrI5 trigonal bipyramid. There are a spread of Sr–I bond distances ranging from 3.19–3.30 Å. There are four inequivalent I1- sites. In the first I1- site, I1- is bonded in a distorted T-shaped geometry to two equivalent Ba2+ and one Sr2+ atom. In the second I1- site, I1- is bonded in a 3-coordinate geometry to one Ba2+ and two equivalent Sr2+ atoms. In the third I1- site, I1- is bonded in a distorted T-shaped geometry to two equivalent Ba2+ and one Sr2+ atom. In the fourth I1- site, I1- is bonded in a 3-coordinate geometry to two equivalent Ba2+ and one Sr2+ atom.
