Materials Data on Pa3Sb by Materials Project
Pa3Sb 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 Sb atoms to form distorted PaPa8Sb4 cuboctahedra that share corners with twelve equivalent PaPa8Sb4 cuboctahedra, edges with eight equivalent SbPa12 cuboctahedra, edges with sixteen equivalent PaPa8Sb4 cuboctahedra, faces with four equivalent SbPa12 cuboctahedra, and faces with fourteen equivalent PaPa8Sb4 cuboctahedra. All Pa–Pa bond lengths are 3.25 Å. All Pa–Sb bond lengths are 3.25 Å. Sb is bonded to twelve equivalent Pa atoms to form SbPa12 cuboctahedra that share corners with twelve equivalent SbPa12 cuboctahedra, edges with twenty-four equivalent PaPa8Sb4 cuboctahedra, faces with six equivalent SbPa12 cuboctahedra, and faces with twelve equivalent PaPa8Sb4 cuboctahedra.
