Abstract

Sr3LaI9 crystallizes in the monoclinic Pc space group. The structure is three-dimensional. there are six inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to seven I1- atoms to form distorted SrI7 pentagonal bipyramids that share corners with two equivalent SrI7 pentagonal bipyramids, corners with two equivalent LaI7 pentagonal bipyramids, and edges with three SrI7 pentagonal bipyramids. There are a spread of Sr–I bond distances ranging from 3.32–3.58 Å. In the second Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight I1- atoms. There are a spread of Sr–I bond distances ranging from 3.26–3.65 Å. In the third Sr2+ site, Sr2+ is bonded to seven I1- atoms to form distorted SrI7 pentagonal bipyramids that share corners with two equivalent SrI7 pentagonal bipyramids, corners with two equivalent LaI7 pentagonal bipyramids, an edgeedge with one SrI7 pentagonal bipyramid, and edges with two equivalent LaI7 pentagonal bipyramids. There are a spread of Sr–I bond distances ranging from 3.32–3.55 Å. In the fourth Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight I1- atoms. There are a spread of Sr–I bond distances ranging from 3.30–3.82 Å. In the fifth Sr2+ site, Sr2+ is bonded in a 8-coordinate geometrymore »« less
