Title: Materials Data on Ba6YBr15 by Materials Project

Abstract

Ba6YBr15 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 Br1- atoms to form a mixture of distorted edge and corner-sharing BaBr6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 7–38°. There are a spread of Ba–Br bond distances ranging from 3.12–3.55 Å. In the second Ba2+ site, Ba2+ is bonded to six Br1- atoms to form BaBr6 octahedra that share corners with three equivalent BaBr6 pentagonal pyramids, a cornercorner with one BaBr5 trigonal bipyramid, a cornercorner with one YBr5 trigonal bipyramid, and edges with three BaBr6 pentagonal pyramids. There are a spread of Ba–Br bond distances ranging from 3.08–3.45 Å. In the third Ba2+ site, Ba2+ is bonded to five Br1- atoms to form distorted BaBr5 trigonal bipyramids that share a cornercorner with one BaBr6 octahedra, corners with three BaBr6 pentagonal pyramids, a cornercorner with one YBr5 trigonal bipyramid, an edgeedge with one BaBr6 pentagonal pyramid, and an edgeedge with one BaBr5 trigonal bipyramid. The corner-sharing octahedral tilt angles are 68°. There are a spread of Ba–Br bond distances ranging from 3.19–3.24 Å.

In the third Br1- site, Br1- is bonded in a distorted trigonal non-coplanar geometry to three Ba2+ atoms. In the fourth Br1- site, Br1- is bonded in a distorted T-shaped geometry to three Ba2+ atoms. In the fifth Br1- site, Br1- is bonded in a distorted T-shaped geometry to three Ba2+ atoms. In the sixth Br1- site, Br1- is bonded in a distorted trigonal planar geometry to three Ba2+ atoms. In the seventh Br1- site, Br1- is bonded in a distorted bent 150 degrees geometry to one Ba2+ and one Y3+ atom. In the eighth Br1- site, Br1- is bonded in a water-like geometry to two Ba2+ atoms. In the ninth Br1- site, Br1- is bonded in a linear geometry to two Ba2+ atoms. In the tenth Br1- site, Br1- is bonded in a bent 120 degrees geometry to one Ba2+ and one Y3+ atom. In the eleventh Br1- site, Br1- is bonded in a bent 120 degrees geometry to one Ba2+ and one Y3+ atom. In the twelfth Br1- site, Br1- is bonded to four Ba2+ atoms to form a mixture of distorted edge and corner-sharing BrBa4 tetrahedra. In the thirteenth Br1- site, Br1- is bonded to four Ba2+ atoms to form a mixture of distorted edge and corner-sharing BrBa4 trigonal pyramids. In the fourteenth Br1- site, Br1- is bonded in a bent 150 degrees geometry to one Ba2+ and one Y3+ atom. In the fifteenth Br1- site, Br1- is bonded in a bent 150 degrees geometry to one Ba2+ and one Y3+ atom.« less
