description: Tb3SOF5 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are six inequivalent Tb3+ sites. In the first Tb3+ site, Tb3+ is bonded in a 9-coordinate geometry to two equivalent S2-, two O2-, and five F1- atoms. Both Tb–S bond lengths are 2.89 Å. There are one shorter (2.33 Å) and one longer (2.36 Å) Tb–O bond lengths. There are a spread of Tb–F bond distances ranging from 2.35–2.45 Å. In the second Tb3+ site, Tb3+ is bonded in a 9-coordinate geometry to two equivalent S2-, one O2-, and six F1- atoms. Both Tb–S bond lengths are 2.89 Å. The Tb–O bond length is 2.25 Å. There are a spread of Tb–F bond distances ranging from 2.30–2.51 Å. In the third Tb3+ site, Tb3+ is bonded in a 9-coordinate geometry to two equivalent S2-, one O2-, and six F1- atoms.
