description: Ho3SOF5 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are six inequivalent Ho3+ sites. In the first Ho3+ site, Ho3+ is bonded in a 9-coordinate geometry to two equivalent S2-, two O2-, and five F1- atoms. Both Ho–S bond lengths are 2.89 Å. There are one shorter (2.30 Å) and one longer (2.35 Å) Ho–O bond lengths. There are two shorter (2.34 Å) and three longer (2.41 Å) Ho–F bond lengths. In the second Ho3+ site, Ho3+ is bonded in a 9-coordinate geometry to two equivalent S2-, one O2-, and six F1- atoms. Both Ho–S bond lengths are 2.87 Å. The Ho–O bond length is 2.23 Å. There are a spread of Ho–F bond distances ranging from 2.28–2.52 Å. In the third Ho3+ site, Ho3+ is bonded in a 9-coordinate geometry to two equivalent S2-, one O2-, and six F1- atoms. Both Ho–S bond lengths are 2.88 Å. The Ho–O bond length is 2.26 Å. There are a spread of Ho–F bond distances ranging from 2.27–2.44 Å. In the fourth Ho3+ site, Ho3+ is bonded in a 7-coordinate geometry to two equivalent S2-, two equivalent O2-, and five F1- atoms. Both Ho–S bond lengths are 3.00 Å. Both Ho–O bond lengths are 2.29 Å.
