Materials Data on BaY2Br8 by Materials Project
Abstract
BaY2Br8 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Ba2+ is bonded in a 8-coordinate geometry to eight Br1- atoms. There are a spread of Ba–Br bond distances ranging from 3.25–3.44 Å. Y3+ is bonded in a 5-coordinate geometry to five Br1- atoms. There are a spread of Y–Br bond distances ranging from 2.60–2.92 Å. There are four inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one Y3+ atom. In the second Br1- site, Br1- is bonded in a 3-coordinate geometry to two equivalent Ba2+ and one Y3+ atom. In the third Br1- site, Br1- is bonded in a 2-coordinate geometry to one Ba2+ and one Y3+ atom. In the fourth Br1- site, Br1- is bonded in a distorted trigonal non-coplanar geometry to one Ba2+ and two equivalent Y3+ atoms.
