Materials Data on SrIF by Materials Project

SrIF is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one SrIF sheet oriented in the (0, 0, 1) direction. Sr2+ is bonded in a 4-coordinate geometry to four equivalent I1- and four equivalent F1- atoms. All Sr–I bond lengths are 3.44 Å. All Sr–F bond lengths are 2.54 Å. I1- is bonded in a 4-coordinate geometry to four equivalent Sr2+ atoms. F1- is bonded to four equivalent Sr2+ atoms to form a mixture of edge and corner-sharing FSr4 tetrahedra.
