HfMnN2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Hf(1) is bonded to six equivalent N(1) atoms to form HfN6 octahedra that share corners with six equivalent Mn(1)N6 octahedra, edges with six equivalent Hf(1)N6 octahedra, and edges with six equivalent Mn(1)N6 octahedra. The corner-sharing octahedral tilt angles are 4°. Mn(1) is bonded to six equivalent N(1) atoms to form MnN6 octahedra that share corners with six equivalent Hf(1)N6 octahedra, edges with six equivalent Hf(1)N6 octahedra, and edges with six equivalent Mn(1)N6 octahedra. The corner-sharing octahedral tilt angles are 4°. N(1) is bonded to three equivalent Hf(1) and three equivalent Mn(1) atoms to form a mixture of edge and corner-sharing NHf3Mn3 octahedra. The corner-sharing octahedra are not tilted.
