PuUN2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Pu(1) is bonded to six equivalent N(1) atoms to form PuN6 octahedra that share corners with six equivalent U(1)N6 octahedra, edges with six equivalent Pu(1)N6 octahedra, and edges with six equivalent U(1)N6 octahedra. The corner-sharing octahedral tilt angles are 4°. U(1) is bonded to six equivalent N(1) atoms to form UN6 octahedra that share corners with six equivalent Pu(1)N6 octahedra, edges with six equivalent Pu(1)N6 octahedra, and edges with six equivalent U(1)N6 octahedra. The corner-sharing octahedral tilt angles are 4°. N(1) is bonded to three equivalent Pu(1) and three equivalent U(1) atoms to form a mixture of corner and edge-sharing NPu3U3 octahedra. The corner-sharing octahedra are not tilted.
