The crystal structure described by PaPm crystallizes in the hexagonal P-6m2 space group. Pa(1) is bonded to six equivalent Pa(1) and six equivalent Pm(1) atoms to form PaPm6Pa6 cuboctahedra that share corners with eighteen equivalent Pa(1)Pm6Pa6 cuboctahedra, edges with six equivalent Pa(1)Pm6Pa6 cuboctahedra, edges with twelve equivalent Pm(1)Pm6Pa6 cuboctahedra, faces with eight equivalent Pa(1)Pm6Pa6 cuboctahedra, and faces with twelve equivalent Pm(1)Pm6Pa6 cuboctahedra.
