Materials Data on ErPa3 by Materials Project

Abstract

Pa3Er 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 Er atoms to form PaEr4Pa8 cuboctahedra that share corners with twelve equivalent PaEr4Pa8 cuboctahedra, edges with eight equivalent ErPa12 cuboctahedra, edges with sixteen equivalent PaEr4Pa8 cuboctahedra, faces with four equivalent ErPa12 cuboctahedra, and faces with fourteen equivalent PaEr4Pa8 cuboctahedra. All Pa–Pa bond lengths are 3.33 Å. All Pa–Er bond lengths are 3.33 Å. Er is bonded to twelve equivalent Pa atoms to form ErPa12 cuboctahedra that share corners with twelve equivalent ErPa12 cuboctahedra, edges with twenty-four equivalent PaEr4Pa8 cuboctahedra, faces with six equivalent ErPa12 cuboctahedra, and faces with twelve equivalent PaEr4Pa8 cuboctahedra.
