Materials Data on La3Pd4 by Materials Project

Abstract

La3Pd4 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. La is bonded in a 9-coordinate geometry to nine Pd atoms. There are a spread of La–Pd bond distances ranging from 2.97–3.46 Å. There are three inequivalent Pd sites. In the first Pd site, Pd is bonded in a 6-coordinate geometry to six equivalent La and two equivalent Pd atoms. Both Pd–Pd bond lengths are 2.94 Å. In the second Pd site, Pd is bonded in a 6-coordinate geometry to six equivalent La and two equivalent Pd atoms. In the third Pd site, Pd is bonded in a 10-coordinate geometry to seven equivalent La and three equivalent Pd atoms. There are one shorter (2.99 Å) and two longer (3.09 Å) Pd–Pd bond lengths.
