Materials Data on Pa3Al by Materials Project

Abstract

Pa3Al is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Pa is bonded to eight equivalent Pa and four equivalent Al atoms to form PaPa8Al4 cuboctahedra that share corners with twelve equivalent PaPa8Al4 cuboctahedra, edges with eight equivalent AlPa12 cuboctahedra, edges with sixteen equivalent PaPa8Al4 cuboctahedra, faces with four equivalent AlPa12 cuboctahedra, and faces with fourteen equivalent PaPa8Al4 cuboctahedra. All Pa–Pa bond lengths are 3.20 Å. All Pa–Al bond lengths are 3.20 Å. Al is bonded to twelve equivalent Pa atoms to form AlPa12 cuboctahedra that share corners with twelve equivalent AlPa12 cuboctahedra, edges with twenty-four equivalent PaPa8Al4 cuboctahedra, faces with six equivalent AlPa12 cuboctahedra, and faces with twelve equivalent PaPa8Al4 cuboctahedra.
