Abstract

Sc4Zr3N8 crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of three Sc4Zr3N8 sheets oriented in the (0, 0, 1) direction. there are two inequivalent Sc3+ sites. In the first Sc3+ site, Sc3+ is bonded in a 6-coordinate geometry to six N3- atoms. There are three shorter (2.04 Å) and three longer (2.55 Å) Sc–N bond lengths. In the second Sc3+ site, Sc3+ is bonded to six N3- atoms to form ScN6 octahedra that share corners with three equivalent ZrN6 octahedra, edges with three equivalent ZrN6 octahedra, and edges with six equivalent ScN6 octahedra. The corner-sharing octahedral tilt angles are 8°. There are three shorter (2.13 Å) and three longer (2.48 Å) Sc–N bond lengths. There are two inequivalent Zr4+ sites. In the first Zr4+ site, Zr4+ is bonded to six N3- atoms to form ZrN6 octahedra that share corners with three equivalent ScN6 octahedra, corners with three equivalent ZrN6 octahedra, edges with three equivalent ScN6 octahedra, and edges with nine ZrN6 octahedra. The corner-sharing octahedra tilt angles range from 0–8°. There are three shorter (2.23 Å) and three longer (2.33 Å) Zr–N bond lengths. In the second Zr4+ site, Zr4+ is bonded to six equivalentmore »« less
