The material structure described by CsI is Halite, Rock Salt structured and crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded to six equivalent I(1) atoms to form a mixture of corner and edge-sharing CsI6 octahedra. The corner-sharing octahedral tilt angles range from 0-4°. I(1) is bonded to six equivalent Cs(1) atoms to form a mixture of corner and edge-sharing ICs6 octahedra. The corner-sharing octahedral tilt angles range from 0-4°. is represented by the CIF card [CIF]
