Abstract

Ba3Y2Br12 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 six Br1- atoms to form distorted BaBr6 pentagonal pyramids that share corners with two equivalent YBr6 octahedra, corners with two equivalent BaBr6 pentagonal pyramids, edges with two equivalent YBr6 octahedra, and an edgeedge with one BaBr6 pentagonal pyramid. The corner-sharing octahedra tilt angles range from 15–47°. There are a spread of Ba–Br bond distances ranging from 3.15–3.70 Å. In the second Ba2+ site, Ba2+ is bonded in a 6-coordinate geometry to six Br1- atoms. There are a spread of Ba–Br bond distances ranging from 3.17–3.65 Å. In the third Ba2+ site, Ba2+ is bonded to six Br1- atoms to form distorted BaBr6 pentagonal pyramids that share corners with two YBr6 octahedra, corners with two equivalent BaBr6 pentagonal pyramids, and edges with two YBr6 octahedra. The corner-sharing octahedra tilt angles range from 54–57°. There are a spread of Ba–Br bond distances ranging from 3.15–3.47 Å. There are two inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded to six Br1- atoms to form YBr6 octahedra that share a cornercorner with one BaBr6more »« less
