Iodine intercalation of a bismuth oxycarbonate, Bi2Sr4Cu2CO3Oz was successfully made. Expansion along the c-axis due to intercalation was estimated to be 3.6 Å per half of the c-dimension in the host material, showing that a stage-1 compound was yielded. Interestingly, the semiconductor host material became superconducting with Tc=23 K due to intercalation. This result can be explained as hole doping from the intercalated iodine to the CuO2 sheet of the pristine compound.
