Materials Data on Pu5Ir3 by Materials Project

Abstract

Pu5Ir3 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent Pu sites. In the first Pu site, Pu is bonded in a 4-coordinate geometry to four equivalent Ir atoms. All Pu–Ir bond lengths are 2.94 Å. In the second Pu site, Pu is bonded in a 6-coordinate geometry to six Ir atoms. There are a spread of Pu–Ir bond distances ranging from 2.89–3.20 Å. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a 10-coordinate geometry to eight equivalent Pu and two equivalent Ir atoms. Both Ir–Ir bond lengths are 2.79 Å. In the second Ir site, Ir is bonded in a 10-coordinate geometry to ten Pu atoms.
