Materials Data on YPu3 by Materials Project
Pu3Y is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Pu sites. In the first Pu site, Pu is bonded to eight Pu and four equivalent Y atoms to form PuY4Pu8 cuboctahedra that share corners with four equivalent YPu12 cuboctahedra, corners with fourteen equivalent PuY4Pu8 cuboctahedra, edges with six equivalent YPu12 cuboctahedra, edges with twelve PuY4Pu8 cuboctahedra, faces with four equivalent YPu12 cuboctahedra, and faces with sixteen PuY4Pu8 cuboctahedra. There are a spread of Pu–Pu bond distances ranging from 3.35–3.51 Å. There are two shorter (3.43 Å) and two longer (3.45 Å) Pu–Y bond lengths. In the second Pu site, Pu is bonded to eight equivalent Pu and four equivalent Y atoms to form PuY4Pu8 cuboctahedra that share corners with four equivalent YPu12 cuboctahedra, corners with fourteen PuY4Pu8 cuboctahedra, edges with six equivalent YPu12 cuboctahedra, edges with twelve equivalent PuY4Pu8 cuboctahedra, faces with four equivalent YPu12 cuboctahedra, and faces with sixteen PuY4Pu8 cuboctahedra. There are two shorter (3.43 Å) and two longer (3.45 Å) Pu–Y bond lengths. Y is bonded to twelve Pu atoms to form YPu12 cuboctahedra that share corners with six equivalent YPu12 cuboctahedra, corners with twelve PuY4Pu8 cuboctahedra, edges with eighteen PuY4Pu8 cuboctahedra, faces with eight equivalent YPu12 cuboctahedra, and faces with twelve PuY4Pu8 cuboctahedra.
