Title: Materials Data on Sr3LaBr9 by Materials Project

Abstract

Sr3LaBr9 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 Br1- atoms to form distorted SrBr7 pentagonal bipyramids that share corners with two equivalent SrBr7 pentagonal bipyramids, corners with two equivalent LaBr7 pentagonal bipyramids, and edges with three SrBr7 pentagonal bipyramids. There are a spread of Sr–Br bond distances ranging from 3.09–3.30 Å. In the second Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight Br1- atoms. There are a spread of Sr–Br bond distances ranging from 3.05–3.37 Å. In the third Sr2+ site, Sr2+ is bonded to seven Br1- atoms to form distorted SrBr7 pentagonal bipyramids that share corners with two equivalent SrBr7 pentagonal bipyramids, corners with two equivalent LaBr7 pentagonal bipyramids, an edgeedge with one SrBr7 pentagonal bipyramid, and edges with two equivalent LaBr7 pentagonal bipyramids.
