Abstract

Sc(TiN)9 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Sc3+ is bonded to six N3- atoms to form ScN6 octahedra that share corners with six TiN5 square pyramids, edges with six TiN6 octahedra, and edges with six TiN5 square pyramids. There are two shorter (2.18 Å) and four longer (2.19 Å) Sc–N bond lengths. There are five inequivalent Ti+2.67+ sites. In the first Ti+2.67+ site, Ti+2.67+ is bonded to five N3- atoms to form TiN5 square pyramids that share corners with two equivalent ScN6 octahedra, corners with seven TiN5 square pyramids, an edgeedge with one ScN6 octahedra, edges with five TiN6 octahedra, and edges with two TiN5 square pyramids. The corner-sharing octahedra tilt angles range from 2–3°. There are a spread of Ti–N bond distances ranging from 2.06–2.13 Å. In the second Ti+2.67+ site, Ti+2.67+ is bonded to six N3- atoms to form TiN6 octahedra that share corners with three TiN6 octahedra, corners with three equivalent TiN5 square pyramids, edges with two equivalent ScN6 octahedra, edges with two TiN6 octahedra, and edges with eight TiN5 square pyramids. The corner-sharing octahedra tilt angles range from 0–3°. There are a spread of Ti–N bond distances ranging from 2.11–2.19 Å.more »« less
