Materials Data on Ba4Ta10CoO30 by Materials Project
Abstract
Ba4Ta10CoO30 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. there are four inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ba–O bond distances ranging from 2.71–2.89 Å. In the second Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to thirteen O2- atoms. There are a spread of Ba–O bond distances ranging from 2.86–3.26 Å. In the third Ba2+ site, Ba2+ is bonded in a 2-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.75–3.02 Å. In the fourth Ba2+ site, Ba2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are two shorter (2.74 Å) and four longer (2.84 Å) Ba–O bond lengths. There are three inequivalent Ta5+ sites. In the first Ta5+ site, Ta5+ is bonded to six O2- atoms to form corner-sharing TaO6 octahedra. The corner-sharing octahedra tilt angles range from 4–35°. There is four shorter (1.98 Å) and two longer (1.99 Å) Ta–O bond length. In the second Ta5+ site, Ta5+ is bonded to six O2- atoms to form corner-sharing TaO6 octahedra. The corner-sharing octahedra tilt angles rangemore »
