The material structure described by HfCoN2 is Caswellsilverite-like structured and crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded to six equivalent N(1) atoms to form distorted HfN6 pentagonal pyramids that share corners with six equivalent Co(1)N6 octahedra, edges with six equivalent Co(1)N6 octahedra, and edges with six equivalent Hf(1)N6 pentagonal pyramids. The corner-sharing octahedral tilt angles are 5°. Co(1) is bonded to six equivalent N(1) atoms to form CoN6 octahedra that share corners with six equivalent Hf(1)N6 pentagonal pyramids, edges with six equivalent Co(1)N6 octahedra, and edges with six equivalent Hf(1)N6 pentagonal pyramids. N(1) is bonded to three equivalent Hf(1) and three equivalent Co(1) atoms to form a mixture of edge, face, and corner-sharing NHf3Co3 octahedra. The corner-sharing octahedral tilt angles range from 0-48°. is represented by the CIF file [CIF]
