The compound described by UPrN2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. 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 Pr(1)N6 octahedra. The corner-sharing octahedra are not tilted. Pr(1) is bonded to two equivalent N(1) and four equivalent N(2) atoms to form PrN6 octahedra that share corners with six equivalent Pr(1)N6 octahedra, edges with four equivalent Pr(1)N6 octahedra, and edges with eight equivalent U(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 four equivalent U(1) and two equivalent Pr(1) atoms to form NPr2U4 octahedra that share corners with six equivalent N(1)Pr2U4 octahedra, edges with four equivalent N(1)Pr2U4 octahedra, and edges with eight equivalent N(2)Pr4U2 octahedra. The corner-sharing octahedra are not tilted. In the second N site, N(2) is bonded to two equivalent U(1) and four equivalent Pr(1) atoms to form NPr4U2 octahedra that share corners with six equivalent N(2)Pr4U2 octahedra, edges with four equivalent N(2)Pr4U2 octahedra, and edges with eight equivalent N(1)Pr2U4 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
