Materials Data on Ba4TiAl3P4(O5F)4 by Materials Project
Abstract
Ba4TiAl3P4(O5F)4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Ba sites. In the first Ba site, Ba is bonded in a 1-coordinate geometry to seven O and two F atoms. There are a spread of Ba–O bond distances ranging from 2.77–3.02 Å. There are one shorter (2.68 Å) and one longer (2.88 Å) Ba–F bond lengths. In the second Ba site, Ba is bonded in a 12-coordinate geometry to ten O and two F atoms. There are a spread of Ba–O bond distances ranging from 2.78–3.47 Å. There are one shorter (2.70 Å) and one longer (2.91 Å) Ba–F bond lengths. Ti is bonded to six O atoms to form TiO6 octahedra that share corners with two equivalent AlO4F2 octahedra and corners with four equivalent PO4 tetrahedra. The corner-sharing octahedral tilt angles are 42°. There are a spread of Ti–O bond distances ranging from 1.90–2.04 Å. There are three inequivalent Al sites. In the first Al site, Al is bonded to four O and two equivalent F atoms to form AlO4F2 octahedra that share corners with two equivalent AlO6 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedral tilt angles aremore »
