LiPa is alpha Samarium-derived structured and crystallizes in the hexagonal P-6m2 space group. Li(1) is bonded to six equivalent Li(1) and six equivalent Pa(1) atoms to form LiLi6Pa6 cuboctahedra that share corners with eighteen equivalent Li(1)Li6Pa6 cuboctahedra, edges with six equivalent Li(1)Li6Pa6 cuboctahedra, edges with twelve equivalent Pa(1)Li6Pa6 cuboctahedra, faces with eight equivalent Li(1)Li6Pa6 cuboctahedra, and faces with twelve equivalent Pa(1)Li6Pa6 cuboctahedra. Pa(1) is bonded to six equivalent Li(1) and six equivalent Pa(1) atoms to form PaLi6Pa6 cuboctahedra that share corners with eighteen equivalent Pa(1)Li6Pa6 cuboctahedra, edges with six equivalent Pa(1)Li6Pa6 cuboctahedra, edges with twelve equivalent Li(1)Li6Pa6 cuboctahedra, faces with eight equivalent Pa(1)Li6Pa6 cuboctahedra, and faces with twelve equivalent Li(1)Li6Pa6 cuboctahedra.
