Abstract

Hf4CN3 is Caswellsilverite-like structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Hf sites. In the first Hf site, Hf is bonded to six N atoms to form a mixture of edge and corner-sharing HfN6 octahedra. The corner-sharing octahedra tilt angles range from 0–2°. All Hf–N bond lengths are 2.27 Å. In the second Hf site, Hf is bonded to three equivalent C and three equivalent N atoms to form a mixture of edge and corner-sharing HfC3N3 octahedra. The corner-sharing octahedra tilt angles range from 0–2°. All Hf–C bond lengths are 2.27 Å. All Hf–N bond lengths are 2.32 Å. C is bonded to six equivalent Hf atoms to form CHf6 octahedra that share corners with six equivalent NHf6 octahedra, edges with six equivalent CHf6 octahedra, and edges with six equivalent NHf6 octahedra. The corner-sharing octahedral tilt angles are 2°. There are two inequivalent N sites. In the first N site, N is bonded to six Hf atoms to form NHf6 octahedra that share corners with three equivalent CHf6 octahedra, corners with three equivalent NHf6 octahedra, edges with three equivalent CHf6 octahedra, and edges with nine NHf6 octahedra.
