Abstract

Ti(NbSe2)3 is Ilmenite-like structured and crystallizes in the hexagonal P6_322 space group. The structure is three-dimensional. Ti4+ is bonded to six equivalent Se2- atoms to form TiSe6 octahedra that share corners with twelve NbSe6 pentagonal pyramids and faces with two equivalent NbSe6 pentagonal pyramids. All Ti–Se bond lengths are 2.59 Å. There are two inequivalent Nb+2.67+ sites. In the first Nb+2.67+ site, Nb+2.67+ is bonded to six equivalent Se2- atoms to form distorted NbSe6 pentagonal pyramids that share corners with six equivalent TiSe6 octahedra and edges with six equivalent NbSe6 pentagonal pyramids. The corner-sharing octahedral tilt angles are 46°. All Nb–Se bond lengths are 2.62 Å. In the second Nb+2.67+ site, Nb+2.67+ is bonded to six equivalent Se2- atoms to form distorted NbSe6 pentagonal pyramids that share corners with three equivalent TiSe6 octahedra, edges with six NbSe6 pentagonal pyramids, and a faceface with one TiSe6 octahedra. The corner-sharing octahedral tilt angles are 46°. There are three shorter (2.62 Å) and three longer (2.64 Å) Nb–Se bond lengths. Se2- is bonded to one Ti4+ and three Nb+2.67+ atoms to form a mixture of distorted edge, corner, and face-sharing SeTiNb3 trigonal pyramids.
