Materials Data on Y3Pu by Materials Project
PuY3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pu is bonded to twelve equivalent Y atoms to form PuY12 cuboctahedra that share corners with six equivalent PuY12 cuboctahedra, corners with twelve equivalent YY8Pu4 cuboctahedra, edges with eighteen equivalent YY8Pu4 cuboctahedra, faces with eight equivalent PuY12 cuboctahedra, and faces with twelve equivalent YY8Pu4 cuboctahedra. There are six shorter (3.43 Å) and six longer (3.60 Å) Pu–Y bond lengths. Y is bonded to four equivalent Pu and eight equivalent Y atoms to form YY8Pu4 cuboctahedra that share corners with four equivalent PuY12 cuboctahedra, corners with fourteen equivalent YY8Pu4 cuboctahedra, edges with six equivalent PuY12 cuboctahedra, edges with twelve equivalent YY8Pu4 cuboctahedra, faces with four equivalent PuY12 cuboctahedra, and faces with sixteen equivalent YY8Pu4 cuboctahedra. There are a spread of Y–Y bond distances ranging from 3.45–3.64 Å.
