The crystal structure described by BaSrI4 crystallizes in the monoclinic C2/c space group. Ba(1) is bonded in a 8-coordinate geometry to four equivalent I(1) and four equivalent I(2) atoms. Sr(1) is bonded in a 8-coordinate geometry to four equivalent I(1) and four equivalent I(2) atoms. There are two inequivalent I sites. In the first I site, I(1) is bonded in a distorted see-saw-like geometry to two equivalent Ba(1) and two equivalent Sr(1) atoms. In the second I site, I(2) is bonded to two equivalent Ba(1) and two equivalent Sr(1) atoms to form a mixture of distorted corner and edge-sharing IBa2Sr2 tetrahedra. is represented by the CIF file [CIF]
