Title: Materials Data on Ba8Nb7S24 by Materials Project

Abstract

Ba8Nb7S24 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are four inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to twelve S2- atoms to form BaS12 cuboctahedra that share corners with six BaS12 cuboctahedra, corners with six NbS6 octahedra, faces with eight BaS12 cuboctahedra, and faces with five NbS6 octahedra. The corner-sharing octahedra tilt angles range from 12–32°. There are a spread of Ba–S bond distances ranging from 3.41–3.54 Å.

The corner-sharing octahedra tilt angles range from 18–22°. There are a spread of Ba–S bond distances ranging from 3.40–3.55 Å. In the third Ba2+ site, Ba2+ is bonded to twelve S2- atoms to form BaS12 cuboctahedra that share corners with six BaS12 cuboctahedra, corners with six NbS6 octahedra, faces with eight BaS12 cuboctahedra, and faces with five NbS6 octahedra.
