Materials Data on LaPdO3 by Materials Project

Abstract

LaPdO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. La2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.41–2.78 Å. Pd4+ is bonded to six O2- atoms to form corner-sharing PdO6 octahedra. The corner-sharing octahedra tilt angles range from 32–37°. There are a spread of Pd–O bond distances ranging from 2.08–2.16 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent La2+ and two equivalent Pd4+ atoms. In the second O2- site, O2- is bonded to two equivalent La2+ and two equivalent Pd4+ atoms to form distorted corner-sharing OLa2Pd2 trigonal pyramids.
