Materials Data on La3Cd(FeO3)4 by Materials Project
La3Cd(FeO3)4 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are three inequivalent La sites. In the first La site, La is bonded in a 3-coordinate geometry to eight O atoms. There are a spread of La–O bond distances ranging from 2.41–2.83 Å. In the second La site, La is bonded in a 12-coordinate geometry to eight O atoms. There are a spread of La–O bond distances ranging from 2.39–2.86 Å. In the third La site, La is bonded in a 9-coordinate geometry to eight O atoms. There are a spread of La–O bond distances ranging from 2.41–2.74 Å. There are two inequivalent Fe sites. In the first Fe site, Fe is bonded to six O atoms to form corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 22–29°. There are a spread of Fe–O bond distances ranging from 1.99–2.07 Å. In the second Fe site, Fe is bonded to six O atoms to form corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 22–31°. There are a spread of Fe–O bond distances ranging from 2.00–2.07 Å. Cd is bonded in a 4-coordinate geometry to four O atoms. There are a spread of Cd–O bond distances ranging from 2.29–2.45 Å. There are eight inequivalent O sites. In the first O site, O is bonded in a 4-coordinate geometry to one La, two equivalent Fe, and one Cd atom. In the second O site, O is bonded in a 4-coordinate geometry to one La, two equivalent Fe, and one Cd atom. In the third O site, O is bonded in a 4-coordinate geometry to two La and two equivalent Fe atoms. In the fourth O site, O is bonded in a 4-coordinate geometry to two La and two equivalent Fe atoms. In the fifth O site, O is bonded in a 3-coordinate geometry to two La and two Fe atoms. In the sixth O site, O is bonded in a 5-coordinate geometry to two La, two Fe, and one Cd atom. In the seventh O site, O is bonded in a 5-coordinate geometry to three La and two Fe atoms. In the eighth O site, O is bonded to two La and two Fe atoms to form distorted edge-sharing OLa2Fe2 trigonal pyramids.
