Materials Data on SrHI by Materials Project
SrHI is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one SrHI sheet oriented in the (0, 0, 1) direction. Sr2+ is bonded in a 8-coordinate geometry to four equivalent H1- and four equivalent I1- atoms. All Sr–H bond lengths are 2.52 Å. All Sr–I bond lengths are 3.42 Å. H1- is bonded to four equivalent Sr2+ atoms to form a mixture of corner and edge-sharing HSr4 tetrahedra. I1- is bonded in a 4-coordinate geometry to four equivalent Sr2+ atoms.
