The structual and superconducting properties of Bi2Sr2Ca1-xYxCu2Oz intercalated with iodine between the Bi-O bilayers were studied. Formation of the stage-1 compound was verified by X-ray analysis, TG analysis and TEM observation. Expansion of the c-axis, which is caused by increase in the distance of the BiO-BiO layers, decreases with decreasing intercalated iodine concentration down to 60%. The expansion of the c-axis of fully intercalated compounds increases with increasing Y content from 7.2 angstrom for x = 0 to 7.5 angstrom for x = 1.O. The temperature dependence of resistivity showed that iodine-doped samples (x = 0 and 0.4) were more semiconductive than non-doped samples. The T(c) of the IBi2Sr2Ca1-xYxCu2Oz series in the over-doped region was reduced by 2-10 K compared with non-intercalated samples.
