The crystal structure described by BaSrI4 crystallizes in the orthorhombic Pna2_1 space group. Ba(1) is bonded in a distorted body-centered cubic geometry to two equivalent I(1), two equivalent I(2), two equivalent I(3), and two equivalent I(4) atoms. Sr(1) is bonded in a 6-coordinate geometry to one I(1), one I(3), two equivalent I(2), and two equivalent I(4) atoms. There are four inequivalent I sites. In the first I site, I(1) is bonded in a trigonal non-coplanar geometry to two equivalent Ba(1) and one Sr(1) atom. In the second I site, I(2) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ba(1) and two equivalent Sr(1) atoms. In the third I site, I(3) is bonded in a trigonal non-coplanar geometry to two equivalent Ba(1) and one Sr(1) atom. In the fourth I site, I(4) is bonded to two equivalent Ba(1) and two equivalent Sr(1) atoms to form distorted corner-sharing IBa2Sr2 tetrahedra. is represented by the CIF file [CIF]
