The material described by PuUN2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. Pu(1) is bonded to two equivalent N(1) and four equivalent N(2) atoms to form PuN6 octahedra that share corners with six equivalent Pu(1)N6 octahedra, edges with four equivalent Pu(1)N6 octahedra, and edges with eight equivalent U(1)N6 octahedra. The corner-sharing octahedra are not tilted. U(1) is bonded to two equivalent N(2) and four equivalent N(1) atoms to form UN6 octahedra that share corners with six equivalent U(1)N6 octahedra, edges with four equivalent U(1)N6 octahedra, and edges with eight equivalent Pu(1)N6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Pu(1) and four equivalent U(1) atoms to form NPu2U4 octahedra that share corners with six equivalent N(1)Pu2U4 octahedra, edges with four equivalent N(1)Pu2U4 octahedra, and edges with eight equivalent N(2)Pu4U2 octahedra. The corner-sharing octahedra are not tilted. In the second N site, N(2) is bonded to four equivalent Pu(1) and two equivalent U(1) atoms to form NPu4U2 octahedra that share corners with six equivalent N(2)Pu4U2 octahedra, edges with four equivalent N(2)Pu4U2 octahedra, and edges with eight equivalent N(1)Pu2U4 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
