Materials Data on GdFe4(BiO4)3 by Materials Project
GdFe4(BiO4)3 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic Pm space group. The structure is three-dimensional. Gd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Gd–O bond distances ranging from 2.29–2.69 Å. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six O2- atoms to form corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 31–34°. There are a spread of Fe–O bond distances ranging from 2.03–2.07 Å. In the second Fe3+ site, Fe3+ is bonded to six O2- atoms to form corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 31–34°. There are a spread of Fe–O bond distances ranging from 2.04–2.08 Å. There are three inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Bi–O bond distances ranging from 2.31–2.71 Å. In the second Bi3+ site, Bi3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Bi–O bond distances ranging from 2.29–2.74 Å. In the third Bi3+ site, Bi3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Bi–O bond distances ranging from 2.31–2.80 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded to one Gd3+, two equivalent Fe3+, and one Bi3+ atom to form distorted corner-sharing OGdFe2Bi tetrahedra. In the second O2- site, O2- is bonded to one Gd3+, two equivalent Fe3+, and one Bi3+ atom to form distorted corner-sharing OGdFe2Bi tetrahedra. In the third O2- site, O2- is bonded to two equivalent Fe3+ and two Bi3+ atoms to form distorted corner-sharing OFe2Bi2 tetrahedra. In the fourth O2- site, O2- is bonded to two equivalent Fe3+ and two Bi3+ atoms to form distorted corner-sharing OFe2Bi2 tetrahedra. In the fifth O2- site, O2- is bonded in a 5-coordinate geometry to one Gd3+, two Fe3+, and two Bi3+ atoms. In the sixth O2- site, O2- is bonded in a 5-coordinate geometry to two Fe3+ and three Bi3+ atoms. In the seventh O2- site, O2- is bonded in a 5-coordinate geometry to one Gd3+, two Fe3+, and two Bi3+ atoms. In the eighth O2- site, O2- is bonded in a 5-coordinate geometry to one Gd3+, two Fe3+, and two Bi3+ atoms.
