Materials Data on BaY2F8 by Materials Project

Kristin Persson
BaY2F8 crystallizes in the tetragonal I-4 space group. The structure is three-dimensional. Ba2+ is bonded in a 4-coordinate geometry to eight F1- atoms. There are four shorter (2.54 Å) and four longer (3.06 Å) Ba–F bond lengths. Y3+ is bonded to six F1- atoms to form corner-sharing YF6 octahedra. The corner-sharing octahedral tilt angles are 44°. There are a spread of Y–F bond distances ranging from 2.11–2.28 Å. There are two inequivalent F1- sites. In...
