Title: Materials Data on Ti(NbSe2)2 by Materials Project

Abstract

Ti(NbSe2)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Ti4+ is bonded to six Se2- atoms to form TiSe6 octahedra that share corners with twelve equivalent NbSe6 octahedra, edges with two equivalent TiSe6 octahedra, and faces with two equivalent NbSe6 octahedra. The corner-sharing octahedra tilt angles range from 51–56°. There are two shorter (2.58 Å) and four longer (2.65 Å) Ti–Se bond lengths. Nb2+ is bonded to six Se2- atoms to form distorted NbSe6 octahedra that share corners with six equivalent TiSe6 octahedra, edges with six equivalent NbSe6 octahedra, and a faceface with one TiSe6 octahedra. The corner-sharing octahedra tilt angles range from 51–56°. There are a spread of Nb–Se bond distances ranging from 2.59–2.87 Å. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 5-coordinate geometry to two equivalent Ti4+ and three equivalent Nb2+ atoms. In the second Se2- site, Se2- is bonded in a 4-coordinate geometry to one Ti4+ and three equivalent Nb2+ atoms.
