Materials Data on BaTa4O11 by Materials Project
BaTa4O11 crystallizes in the hexagonal P6_322 space group. The structure is three-dimensional. Ba2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are six shorter (2.64 Å) and two longer (2.73 Å) Ba–O bond lengths. There are two inequivalent Ta5+ sites. In the first Ta5+ site, Ta5+ is bonded in a 7-coordinate geometry to six O2- atoms. There are a spread of Ta–O bond distances ranging from 1.98–2.10 Å. In the second Ta5+ site, Ta5+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Ta–O bond lengths are 2.00 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Ta5+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Ba2+ and two Ta5+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to one Ba2+ and three equivalent Ta5+ atoms.
