description: Y3SOF5 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are six inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded in a 9-coordinate geometry to two equivalent S2-, two O2-, and five F1- atoms. Both Y–S bond lengths are 2.89 Å. There are one shorter (2.31 Å) and one longer (2.36 Å) Y–O bond lengths. There are a spread of Y–F bond distances ranging from 2.35–2.44 Å. In the second Y3+ site, Y3+ is bonded in a 9-coordinate geometry to two equivalent S2-, one O2-, and six F1- atoms. Both Y–S bond lengths are 2.88 Å. The Y–O bond length is 2.25 Å. There are a spread of Y–F bond distances ranging from 2.30–2.51 Å. In the third Y3+ site, Y3+ is bonded in a 9-coordinate geometry to two equivalent S2-, one O2-, and six F1- atoms. Both Y–S bond lengths are 2.89 Å. The Y–O bond length is 2.27 Å. There are a spread of Y–F bond distances ranging from 2.29–2.46 Å. In the fourth Y3+ site, Y3+ is bonded in a 7-coordinate geometry to two equivalent S2-, two equivalent O2-, and five F1- atoms. Both Y–S bond lengths are 3.01 Å. Both Y–O bond lengths are 2.31 Å.
