Materials Data on PuCd11 by Materials Project

Abstract

PuCd11 crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Pu is bonded in a 12-coordinate geometry to twenty Cd atoms. There are a spread of Pu–Cd bond distances ranging from 3.59–3.89 Å. There are five inequivalent Cd sites. In the first Cd site, Cd is bonded in a cuboctahedral geometry to twelve Cd atoms. All Cd–Cd bond lengths are 3.15 Å. In the second Cd site, Cd is bonded in a 6-coordinate geometry to three equivalent Pu and six Cd atoms. All Cd–Cd bond lengths are 2.95 Å. In the third Cd site, Cd is bonded in a distorted q6 geometry to two equivalent Pu and eight Cd atoms. There are two shorter (2.95 Å) and four longer (3.03 Å) Cd–Cd bond lengths. In the fourth Cd site, Cd is bonded in a 10-coordinate geometry to one Pu and nine Cd atoms. All Cd–Cd bond lengths are 3.15 Å. In the fifth Cd site, Cd is bonded in a 10-coordinate geometry to one Pu and nine Cd atoms. There are four shorter (3.03 Å) and four longer (3.15 Å) Cd–Cd bond lengths.
