The crystal structure described by CsSrI3 is (Cubic) Perovskite structured and crystallizes in the monoclinic Cm space group. Cs(1) is bonded in a 5-coordinate geometry to one I(2) and four equivalent I(1) atoms. Sr(1) is bonded to two equivalent I(2) and four equivalent I(1) atoms to form corner-sharing SrI6 octahedra. The corner-sharing octahedral tilt angles range from 2-6°. There are two inequivalent I sites. In the first I site, I(1) is bonded in a linear geometry to two equivalent Cs(1) and two equivalent Sr(1) atoms. In the second I site, I(2) is bonded in a distorted linear geometry to one Cs(1) and two equivalent Sr(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
