Title: Materials Data on CsTaSe3 by Materials Project

Abstract

CsTaSe3 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded to twelve Se2- atoms to form CsSe12 cuboctahedra that share corners with six CsSe12 cuboctahedra, corners with six TaSe6 octahedra, faces with eight CsSe12 cuboctahedra, and faces with six TaSe6 octahedra. The corner-sharing octahedra tilt angles range from 13–21°. There are a spread of Cs–Se bond distances ranging from 3.85–3.92 Å. In the second Cs1+ site, Cs1+ is bonded to twelve Se2- atoms to form CsSe12 cuboctahedra that share corners with six CsSe12 cuboctahedra, corners with six TaSe6 octahedra, faces with eight CsSe12 cuboctahedra, and faces with six TaSe6 octahedra. The corner-sharing octahedra tilt angles range from 11–22°. There are a spread of Cs–Se bond distances ranging from 3.85–3.93 Å. In the third Cs1+ site, Cs1+ is bonded to twelve Se2- atoms to form CsSe12 cuboctahedra that share corners with six CsSe12 cuboctahedra, corners with six TaSe6 octahedra, faces with eight CsSe12 cuboctahedra, and faces with six TaSe6 octahedra.
