Materials Data on HoSF by Materials Project
HoSF is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ho3+ is bonded in a 9-coordinate geometry to five equivalent S2- and four equivalent F1- atoms. There are four shorter (2.80 Å) and one longer (2.84 Å) Ho–S bond lengths. All Ho–F bond lengths are 2.45 Å. S2- is bonded in a 5-coordinate geometry to five equivalent Ho3+ atoms. F1- is bonded to four equivalent Ho3+ atoms to form a mixture of distorted corner and edge-sharing FHo4 tetrahedra.
