Materials Data on Nd2PdO4 by Materials Project

Abstract

Nd2PdO4 is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Nd3+ is bonded in a 1-coordinate geometry to nine O2- atoms. There are a spread of Nd–O bond distances ranging from 2.21–2.90 Å. Pd2+ is bonded to six O2- atoms to form corner-sharing PdO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (1.99 Å) and two longer (2.47 Å) Pd–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Nd3+ and two equivalent Pd2+ atoms to form a mixture of distorted edge, corner, and face-sharing ONd4Pd2 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second O2- site, O2- is bonded in a 1-coordinate geometry to five equivalent Nd3+ and one Pd2+ atom.
