Vitreous SexI1-x samples x0.l 0.15 0.20 have been prepared and studied by thermal analysis, iodometry, X-ray diffraction and optical transmission. The results show that part of iodine remains unbonded in the structure while another part saturates the ends of selenium chains. The main effect of the iodine atoms upon the selenium matrix configuration consists in the shortening of the selenium chains and occupation of the short chain ends by atomic iodine.
