ThPrN2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. Th(1) is bonded to two equivalent N(2) and four equivalent N(1) atoms to form ThN6 octahedra that share corners with six equivalent Th(1)N6 octahedra, edges with four equivalent Th(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 Th(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 Th(1) and two equivalent Pr(1) atoms to form NPr2Th4 octahedra that share corners with six equivalent N(1)Pr2Th4 octahedra, edges with four equivalent N(1)Pr2Th4 octahedra, and edges with eight equivalent N(2)Pr4Th2 octahedra. The corner-sharing octahedra are not tilted. In the second N site, N(2) is bonded to two equivalent Th(1) and four equivalent Pr(1) atoms to form NPr4Th2 octahedra that share corners with six equivalent N(2)Pr4Th2 octahedra, edges with four equivalent N(2)Pr4Th2 octahedra, and edges with eight equivalent N(1)Pr2Th4 octahedra. The corner-sharing octahedra are not tilted.
