Materials Data on TmPa3 by Materials Project

Abstract

Pa3Tm 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 Tm atoms to form PaTm4Pa8 cuboctahedra that share corners with twelve equivalent PaTm4Pa8 cuboctahedra, edges with eight equivalent TmPa12 cuboctahedra, edges with sixteen equivalent PaTm4Pa8 cuboctahedra, faces with four equivalent TmPa12 cuboctahedra, and faces with fourteen equivalent PaTm4Pa8 cuboctahedra. All Pa–Pa bond lengths are 3.33 Å. All Pa–Tm bond lengths are 3.33 Å. Tm is bonded to twelve equivalent Pa atoms to form TmPa12 cuboctahedra that share corners with twelve equivalent TmPa12 cuboctahedra, edges with twenty-four equivalent PaTm4Pa8 cuboctahedra, faces with six equivalent TmPa12 cuboctahedra, and faces with twelve equivalent PaTm4Pa8 cuboctahedra.
