Materials Data on La6P17Pd6 by Materials Project

Abstract

La6Pd6P17 crystallizes in the cubic I-43m space group. The structure is three-dimensional. La+2.50+ is bonded in a 7-coordinate geometry to nine P+1.59- atoms. There are a spread of La–P bond distances ranging from 3.00–3.45 Å. Pd2+ is bonded in a square co-planar geometry to four equivalent P+1.59- atoms. All Pd–P bond lengths are 2.36 Å. There are three inequivalent P+1.59- sites. In the first P+1.59- site, P+1.59- is bonded in a 5-coordinate geometry to three equivalent La+2.50+, two equivalent Pd2+, and one P+1.59- atom. The P–P bond length is 2.22 Å. In the second P+1.59- site, P+1.59- is bonded in a 6-coordinate geometry to three equivalent La+2.50+ and three equivalent P+1.59- atoms. In the third P+1.59- site, P+1.59- is bonded in an octahedral geometry to six equivalent La+2.50+ atoms.
