ThDyN2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Th(1) is bonded to six equivalent N(1) atoms to form ThN6 octahedra that share corners with six equivalent Dy(1)N6 octahedra, edges with six equivalent Th(1)N6 octahedra, and edges with six equivalent Dy(1)N6 octahedra. The corner-sharing octahedral tilt angles are 1°. Dy(1) is bonded to six equivalent N(1) atoms to form DyN6 octahedra that share corners with six equivalent Th(1)N6 octahedra, edges with six equivalent Th(1)N6 octahedra, and edges with six equivalent Dy(1)N6 octahedra. The corner-sharing octahedral tilt angles are 1°. N(1) is bonded to three equivalent Th(1) and three equivalent Dy(1) atoms to form a mixture of corner and edge-sharing NDy3Th3 octahedra. The corner-sharing octahedra are not tilted.
