The compound described by PuNpB4 is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6/mmm space group. Pu(1) is bonded to twelve equivalent B(1) atoms to form PuB12 cuboctahedra that share edges with twelve equivalent Np(1)B12 cuboctahedra, faces with two equivalent Np(1)B12 cuboctahedra, and faces with six equivalent Pu(1)B12 cuboctahedra. Np(1) is bonded to twelve equivalent B(1) atoms to form NpB12 cuboctahedra that share edges with twelve equivalent Pu(1)B12 cuboctahedra, faces with two equivalent Pu(1)B12 cuboctahedra, and faces with six equivalent Np(1)B12 cuboctahedra. B(1) is bonded in a 9-coordinate geometry to three equivalent Pu(1), three equivalent Np(1), and three equivalent B(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
