Materials Data on SmPu by Materials Project

Abstract

PuSm crystallizes in the monoclinic Pm space group. The structure is three-dimensional. Pu is bonded to six equivalent Pu and six equivalent Sm atoms to form PuSm6Pu6 cuboctahedra that share corners with eighteen equivalent PuSm6Pu6 cuboctahedra, edges with six equivalent PuSm6Pu6 cuboctahedra, edges with twelve equivalent SmSm6Pu6 cuboctahedra, faces with eight equivalent PuSm6Pu6 cuboctahedra, and faces with twelve equivalent SmSm6Pu6 cuboctahedra. There are a spread of Pu–Pu bond distances ranging from 3.57–3.63 Å. There are four shorter (3.61 Å) and two longer (3.63 Å) Pu–Sm bond lengths.
