Materials Data on SrBrF by Materials Project
SrFBr is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Sr2+ is bonded in a 9-coordinate geometry to five equivalent Br1- and four equivalent F1- atoms. There are four shorter (3.26 Å) and one longer (3.47 Å) Sr–Br bond lengths. All Sr–F bond lengths are 2.54 Å. Br1- is bonded in a 5-coordinate geometry to five equivalent Sr2+ and four equivalent F1- atoms. All Br–F bond lengths are 3.40 Å. F1- is bonded to four equivalent Sr2+ and four equivalent Br1- atoms to form a mixture of face and edge-sharing FSr4Br4 tetrahedra.
