Materials Data on Pa3Cd by Materials Project

Abstract

Pa3Cd 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 Cd atoms to form PaPa8Cd4 cuboctahedra that share corners with twelve equivalent PaPa8Cd4 cuboctahedra, edges with eight equivalent CdPa12 cuboctahedra, edges with sixteen equivalent PaPa8Cd4 cuboctahedra, faces with four equivalent CdPa12 cuboctahedra, and faces with fourteen equivalent PaPa8Cd4 cuboctahedra. All Pa–Pa bond lengths are 3.27 Å. All Pa–Cd bond lengths are 3.27 Å. Cd is bonded to twelve equivalent Pa atoms to form CdPa12 cuboctahedra that share corners with twelve equivalent CdPa12 cuboctahedra, edges with twenty-four equivalent PaPa8Cd4 cuboctahedra, faces with six equivalent CdPa12 cuboctahedra, and faces with twelve equivalent PaPa8Cd4 cuboctahedra.
