Materials Data on BaAlF5 by Materials Project
BaAlF5 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Ba2+ is bonded in a 11-coordinate geometry to eleven F1- atoms. There are a spread of Ba–F bond distances ranging from 2.66–3.25 Å. Al3+ is bonded to six F1- atoms to form corner-sharing AlF6 octahedra. The corner-sharing octahedral tilt angles are 30°. There are a spread of Al–F bond distances ranging from 1.79–1.91 Å. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 150 degrees geometry to one Ba2+ and two equivalent Al3+ atoms. In the second F1- site, F1- is bonded in a distorted single-bond geometry to three equivalent Ba2+ and one Al3+ atom. In the third F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Ba2+ and one Al3+ atom. In the fourth F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Ba2+ and one Al3+ atom. In the fifth F1- site, F1- is bonded in a distorted single-bond geometry to three equivalent Ba2+ and one Al3+ atom.
