Materials Data on Ce(PPt2)2 by Materials Project

Abstract

Ce(Pt2P)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ce4+ is bonded in a 9-coordinate geometry to nine Pt2- atoms. There are a spread of Ce–Pt bond distances ranging from 3.10–3.25 Å. There are four inequivalent Pt2- sites. In the first Pt2- site, Pt2- is bonded in a 3-coordinate geometry to four equivalent Ce4+ and three P2+ atoms. There are a spread of Pt–P bond distances ranging from 2.34–2.45 Å. In the second Pt2- site, Pt2- is bonded in a 2-coordinate geometry to one Ce4+ and three equivalent P2+ atoms. There are two shorter (2.35 Å) and one longer (2.69 Å) Pt–P bond lengths. In the third Pt2- site, Pt2- is bonded in a 12-coordinate geometry to two equivalent Ce4+ and three P2+ atoms. There are two shorter (2.41 Å) and one longer (2.81 Å) Pt–P bond lengths. In the fourth Pt2- site, Pt2- is bonded in a 2-coordinate geometry to two equivalent Ce4+ and two P2+ atoms. There are one shorter (2.33 Å) and one longer (2.40 Å) Pt–P bond lengths. There are two inequivalent P2+ sites. In the first P2+ site, P2+ is bonded in a 5-coordinate geometry to five Pt2- atoms. In the second P2+ site, P2+ is bonded in a 6-coordinate geometry to six Pt2- atoms.
