Materials Data on Ca2FeSbO6 by Materials Project
Ca2FeSbO6 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.35–2.75 Å. In the second Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.33–2.74 Å. Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with two equivalent FeO6 octahedra and corners with four equivalent SbO6 octahedra. The corner-sharing octahedra tilt angles range from 28–31°. There are a spread of Fe–O bond distances ranging from 2.01–2.10 Å. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with two equivalent SbO6 octahedra and corners with four equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 31–34°. There are a spread of Sb–O bond distances ranging from 1.99–2.04 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three Ca2+, one Fe3+, and one Sb5+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three Ca2+, one Fe3+, and one Sb5+ atom. In the third O2- site, O2- is bonded to two Ca2+ and two equivalent Sb5+ atoms to form distorted corner-sharing OCa2Sb2 tetrahedra. In the fourth O2- site, O2- is bonded to two Ca2+ and two equivalent Fe3+ atoms to form distorted corner-sharing OCa2Fe2 tetrahedra.
