Materials Data on Eu(PIr)2 by Materials Project

Abstract

Eu(IrP)2 crystallizes in the trigonal P3_221 space group. The structure is three-dimensional. Eu is bonded in a 11-coordinate geometry to five Ir and six equivalent P atoms. There are a spread of Eu–Ir bond distances ranging from 3.18–3.35 Å. There are a spread of Eu–P bond distances ranging from 3.06–3.18 Å. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a 12-coordinate geometry to three equivalent Eu and four equivalent P atoms. There are two shorter (2.35 Å) and two longer (2.40 Å) Ir–P bond lengths. In the second Ir site, Ir is bonded in a 6-coordinate geometry to two equivalent Eu and four equivalent P atoms. There are two shorter (2.27 Å) and two longer (2.33 Å) Ir–P bond lengths. P is bonded to three equivalent Eu and four Ir atoms to form a mixture of distorted face, edge, and corner-sharing PEu3Ir4 pentagonal bipyramids.
