Materials Data on K3GaS3 by Materials Project
K3GaS3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 5-coordinate geometry to five S2- atoms. There are a spread of K–S bond distances ranging from 3.15–3.63 Å. In the second K1+ site, K1+ is bonded in a 7-coordinate geometry to seven S2- atoms. There are a spread of K–S bond distances ranging from 3.22–3.85 Å. In the third K1+ site, K1+ is bonded in a 4-coordinate geometry to five S2- atoms. There are a spread of K–S bond distances ranging from 3.14–3.51 Å. Ga3+ is bonded to four S2- atoms to form edge-sharing GaS4 tetrahedra. There are a spread of Ga–S bond distances ranging from 2.27–2.38 Å. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a 6-coordinate geometry to four K1+ and two equivalent Ga3+ atoms. In the second S2- site, S2- is bonded in a 1-coordinate geometry to six K1+ and one Ga3+ atom. In the third S2- site, S2- is bonded in a 1-coordinate geometry to seven K1+ and one Ga3+ atom.
