Abstract

Ba6YI15 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are six inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to six I1- atoms to form a mixture of distorted edge and corner-sharing BaI6 octahedra. The corner-sharing octahedra tilt angles range from 10–35°. There are a spread of Ba–I bond distances ranging from 3.34–3.80 Å. In the second Ba2+ site, Ba2+ is bonded to six I1- atoms to form BaI6 octahedra that share corners with three equivalent BaI6 octahedra, a cornercorner with one BaI5 trigonal bipyramid, a cornercorner with one YI5 trigonal bipyramid, and edges with three BaI6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 10–35°. There are a spread of Ba–I bond distances ranging from 3.29–3.67 Å.

In the eleventh I1- site, I1- is bonded in a bent 120 degrees geometry to one Ba2+ and one Y3+ atom. In the twelfth I1- site, I1- is bonded to four Ba2+ atoms to form a mixture of distorted edge and corner-sharing IBa4 tetrahedra. In the thirteenth I1- site, I1- is bonded to four Ba2+ atoms to form a mixture of distorted edge and corner-sharing IBa4 trigonal pyramids. In the fourteenth I1- site, I1- is bonded in a bent 150 degrees geometry to one Ba2+ and one Y3+ atom.
