Ba3Ta2S8 crystallizes in the monoclinic P2/m space group. The structure is three-dimensional. there are five inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a distorted body-centered cubic geometry to eight S2- atoms. There are four shorter (3.28 Å) and four longer (3.29 Å) Ba–S bond lengths. In the second Ba2+ site, Ba2+ is bonded in a 11-coordinate geometry to eleven S2- atoms. There are a spread of Ba–S bond distances ranging from 3.20–3.52 Å. In the third Ba2+ site, Ba2+ is bonded in a 10-coordinate geometry to ten S2- atoms. There are a spread of Ba–S bond distances ranging from 3.20–3.53 Å. In the fourth Ba2+ site, Ba2+ is bonded in a 10-coordinate geometry to ten S2- atoms. There are a spread of Ba–S bond distances ranging from 3.20–3.53 Å. In the fifth Ba2+ site, Ba2+ is bonded in a 11-coordinate geometry to eleven S2- atoms. There are a spread of Ba–S bond distances ranging from 3.20–3.65 Å. There are four inequivalent Ta5+ sites. In the first Ta5+ site, Ta5+ is bonded to six S2- atoms to form face-sharing TaS6 octahedra. There are two shorter (2.42 Å) and four longer (2.47 Å) Ta–S bond lengths. In the second Ta5+ site, Ta5+ is bonded to six S2- atoms to form face-sharing TaS6 octahedra. There are two shorter (2.42 Å) and four longer (2.47 Å) Ta–S bond lengths. In the third Ta5+ site, Ta5+ is bonded to six S2- atoms to form face-sharing TaS6 octahedra. There are a spread of Ta–S bond distances ranging from 2.31–2.66 Å. In the fourth Ta5+ site, Ta5+ is bonded to six S2- atoms to form distorted face-sharing TaS6 octahedra. There are a spread of Ta–S bond distances ranging from 2.31–2.66 Å. There are eight inequivalent S2- sites. In the first S2- site, S2- is bonded in a 1-coordinate geometry to four Ba2+ and one Ta5+ atom. In the second S2- site, S2- is bonded in a 1-coordinate geometry to four Ba2+ and one Ta5+ atom. In the third S2- site, S2- is bonded in a 5-coordinate geometry to three Ba2+ and two Ta5+ atoms. In the fourth S2- site, S2- is bonded in a 1-coordinate geometry to four Ba2+ and one Ta5+ atom. In the fifth S2- site, S2- is bonded in a distorted single-bond geometry to four Ba2+ and one Ta5+ atom. In the sixth S2- site, S2- is bonded in a 6-coordinate geometry to four Ba2+ and two Ta5+ atoms. In the seventh S2- site, S2- is bonded in a 6-coordinate geometry to four Ba2+ and two Ta5+ atoms. In the eighth S2- site, S2- is bonded in a 5-coordinate geometry to three Ba2+ and two Ta5+ atoms.
