The material described by UPrN2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. U(1) is bonded to six equivalent N(1) atoms to form UN6 octahedra that share corners with six equivalent Pr(1)N6 octahedra, edges with six equivalent U(1)N6 octahedra, and edges with six equivalent Pr(1)N6 octahedra. The corner-sharing octahedral tilt angles are 10°. Pr(1) is bonded to six equivalent N(1) atoms to form PrN6 octahedra that share corners with six equivalent U(1)N6 octahedra, edges with six equivalent U(1)N6 octahedra, and edges with six equivalent Pr(1)N6 octahedra. The corner-sharing octahedral tilt angles are 10°. N(1) is bonded to three equivalent U(1) and three equivalent Pr(1) atoms to form a mixture of corner and edge-sharing NPr3U3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
