Materials Data on PuAl3 by Materials Project

Abstract

PuAl3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Pu is bonded to twelve equivalent Al atoms to form PuAl12 cuboctahedra that share corners with twelve equivalent PuAl12 cuboctahedra, edges with twenty-four equivalent AlPu4Al8 cuboctahedra, faces with six equivalent PuAl12 cuboctahedra, and faces with twelve equivalent AlPu4Al8 cuboctahedra. All Pu–Al bond lengths are 2.96 Å. Al is bonded to four equivalent Pu and eight equivalent Al atoms to form AlPu4Al8 cuboctahedra that share corners with twelve equivalent AlPu4Al8 cuboctahedra, edges with eight equivalent PuAl12 cuboctahedra, edges with sixteen equivalent AlPu4Al8 cuboctahedra, faces with four equivalent PuAl12 cuboctahedra, and faces with fourteen equivalent AlPu4Al8 cuboctahedra. All Al–Al bond lengths are 2.96 Å.
