Abstract

Ba3(YI6)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to five I1- atoms to form distorted BaI5 square pyramids that share corners with three YI6 octahedra, a cornercorner with one BaI6 pentagonal pyramid, and an edgeedge with one YI6 octahedra. The corner-sharing octahedra tilt angles range from 24–69°. There are a spread of Ba–I bond distances ranging from 3.35–3.72 Å. In the second Ba2+ site, Ba2+ is bonded in a 5-coordinate geometry to five I1- atoms. There are a spread of Ba–I bond distances ranging from 3.38–3.62 Å. In the third Ba2+ site, Ba2+ is bonded to six I1- atoms to form distorted BaI6 pentagonal pyramids that share corners with two YI6 octahedra, a cornercorner with one BaI5 square pyramid, and edges with two YI6 octahedra. The corner-sharing octahedra tilt angles range from 51–52°. There are a spread of Ba–I bond distances ranging from 3.39–3.63 Å. There are two inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded to six I1- atoms to form YI6 octahedra that share a cornercorner with one BaI6 pentagonal pyramid, a cornercorner with one BaI5 squaremore »« less
