Abstract

Ba5La3I19 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are five inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to seven I1- atoms to form distorted BaI7 pentagonal bipyramids that share corners with four LaI6 octahedra, a cornercorner with one BaI6 pentagonal pyramid, and an edgeedge with one LaI6 octahedra. The corner-sharing octahedra tilt angles range from 32–62°. There are a spread of Ba–I bond distances ranging from 3.42–3.76 Å. In the second Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight I1- atoms. There are a spread of Ba–I bond distances ranging from 3.52–4.17 Å. In the third Ba2+ site, Ba2+ is bonded in a 6-coordinate geometry to six I1- atoms. There are a spread of Ba–I bond distances ranging from 3.39–3.79 Å.
