Materials Data on Ba2InO3F by Materials Project
Ba2InO3F crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.60–3.06 Å. In the second Ba2+ site, Ba2+ is bonded in a 9-coordinate geometry to four equivalent O2- and five equivalent F1- atoms. All Ba–O bond lengths are 2.72 Å. There are one shorter (2.73 Å) and four longer (3.07 Å) Ba–F bond lengths. In3+ is bonded in a 5-coordinate geometry to five O2- and one F1- atom. There are one shorter (2.13 Å) and four longer (2.15 Å) In–O bond lengths. The In–F bond length is 2.78 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to four Ba2+ and two equivalent In3+ atoms. In the second O2- site, O2- is bonded to five equivalent Ba2+ and one In3+ atom to form a mixture of distorted edge and corner-sharing OBa5In octahedra. The corner-sharing octahedral tilt angles are 11°. F1- is bonded in a 6-coordinate geometry to five equivalent Ba2+ and one In3+ atom.
