description: Ba3LaCl9 crystallizes in the monoclinic Pc space group. The structure is three-dimensional. there are six inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to seven Cl1- atoms to form distorted BaCl7 pentagonal bipyramids that share corners with two equivalent LaCl7 pentagonal bipyramids. There are a spread of Ba–Cl bond distances ranging from 3.09–3.23 Å. In the second Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of Ba–Cl bond distances ranging from 3.07–3.33 Å. In the third Ba2+ site, Ba2+ is bonded in a 7-coordinate geometry to seven Cl1- atoms. There are a spread of Ba–Cl bond distances ranging from 3.04–3.24 Å. In the fourth Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of Ba–Cl bond distances ranging from 3.06–3.39 Å. In the fifth Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight Cl1- atoms.
