Abstract

ZrNb4CN4 is alpha Po-derived structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. Zr2+ is bonded to three equivalent C4- and three equivalent N3- atoms to form ZrC3N3 octahedra that share corners with six NbC3N3 octahedra, edges with six equivalent ZrC3N3 octahedra, and edges with six NbC3N3 octahedra. The corner-sharing octahedral tilt angles are 3°. All Zr–C bond lengths are 2.29 Å. All Zr–N bond lengths are 2.33 Å. There are four inequivalent Nb+3.50+ sites. In the first Nb+3.50+ site, Nb+3.50+ is bonded to three equivalent C4- and three equivalent N3- atoms to form NbC3N3 octahedra that share corners with three equivalent ZrC3N3 octahedra, corners with three equivalent NbN6 octahedra, edges with three equivalent ZrC3N3 octahedra, and edges with nine NbC3N3 octahedra. The corner-sharing octahedral tilt angles are 3°. All Nb–C bond lengths are 2.21 Å. All Nb–N bond lengths are 2.30 Å. In the second Nb+3.50+ site, Nb+3.50+ is bonded to six N3- atoms to form a mixture of corner and edge-sharing NbN6 octahedra. The corner-sharing octahedra tilt angles range from 1–3°. There are three shorter (2.22 Å) and three longer (2.25 Å) Nb–N bond lengths. In the third Nb+3.50+ site, Nb+3.50+ is bonded tomore »« less
