Abstract Iodine-intercalated high-T c oxide Bi2Sr2CaCu2O y was studied at 16 K using129I Mössbauer effect. The Mössbauer spectrum shows the presence of I 3 − ions which have an almost linear structure and a symmetrical charge population, and no other iodine species are found. In addition to the electronic structure of each iodine species, the analysis of the intensity ratios of the quadrupole-split transitions reveals information about the anisotropy of the recoilless fraction for each iodine atom. It cannot exclude the possibility that the I 3 − ion is slightly asymmetrical and/or bent with consideration to small interactions between the I 3 − ion and the neighboring Bi-O layers.
