Title: Materials Data on BaSrI4 by Materials Project

Abstract

BaSrI4 is Hydrophilite-derived structured and crystallizes in the orthorhombic Pnna space group. The structure is three-dimensional. Ba2+ is bonded to six I1- atoms to form distorted BaI6 pentagonal pyramids that share corners with eight equivalent SrI6 octahedra and edges with two equivalent BaI6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 32–69°. There are a spread of Ba–I bond distances ranging from 3.39–3.56 Å. Sr2+ is bonded to six I1- atoms to form SrI6 octahedra that share corners with eight equivalent BaI6 pentagonal pyramids and edges with two equivalent SrI6 octahedra. There are a spread of Sr–I bond distances ranging from 3.26–3.37 Å. There are two inequivalent I1- sites. In the first I1- site, I1- is bonded in a 3-coordinate geometry to two equivalent Ba2+ and one Sr2+ atom. In the second I1- site, I1- is bonded in a distorted trigonal planar geometry to one Ba2+ and two equivalent Sr2+ atoms.
