Materials Data on Ce6P17Pd6 by Materials Project

Abstract

Ce6Pd6P17 crystallizes in the cubic I-43m space group. The structure is three-dimensional. Ce+3.17+ is bonded in a 7-coordinate geometry to seven P+2.06- atoms. There are a spread of Ce–P bond distances ranging from 2.92–3.17 Å. Pd+2.67+ is bonded in a square co-planar geometry to four equivalent P+2.06- atoms. All Pd–P bond lengths are 2.36 Å. There are three inequivalent P+2.06- sites. In the first P+2.06- site, P+2.06- is bonded in a 5-coordinate geometry to two equivalent Ce+3.17+, two equivalent Pd+2.67+, and one P+2.06- atom. The P–P bond length is 2.22 Å. In the second P+2.06- site, P+2.06- is bonded to three equivalent Ce+3.17+ and three equivalent P+2.06- atoms to form distorted PCe3P3 pentagonal pyramids that share corners with three equivalent PCe3P3 pentagonal pyramids and a faceface with one PCe6 octahedra. In the third P+2.06- site, P+2.06- is bonded to six equivalent Ce+3.17+ atoms to form face-sharing PCe6 octahedra.
