Materials Data on TbPa by Materials Project
PaTb crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Pa is bonded to six equivalent Pa and six equivalent Tb atoms to form PaTb6Pa6 cuboctahedra that share corners with eighteen equivalent PaTb6Pa6 cuboctahedra, edges with six equivalent PaTb6Pa6 cuboctahedra, edges with twelve equivalent TbTb6Pa6 cuboctahedra, faces with eight equivalent PaTb6Pa6 cuboctahedra, and faces with twelve equivalent TbTb6Pa6 cuboctahedra. All Pa–Pa bond lengths are 3.30 Å. All Pa–Tb bond lengths are 3.48 Å.
