The compound described by BaSrI4 is Fluorite-derived structured and crystallizes in the tetragonal I4_1/a space group. Ba(1) is bonded in a body-centered cubic geometry to eight equivalent I(1) atoms. Sr(1) is bonded in a body-centered cubic geometry to eight equivalent I(1) atoms. I(1) is bonded to two equivalent Ba(1) and two equivalent Sr(1) atoms to form a mixture of corner and edge-sharing IBa2Sr2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
