The benzene‐mediated iodine intercalation into the pseudo‐layered superconductor Bi2Sr1.8Ca1.2Cu2Ox (2212) is an efficient way to prepare an intercalate with nominal composition IBi2Sr1.8Ca1.2Cu2Ox. Expansion by 22 percent along the crystallographic c‐axis was observed but both a‐and b‐axes of the intercalates remained unchanged. The superconducting temperature (Tc) of 2212 phase decreased 10 K upon iodine intercalation. We report the First solvent‐mediated intercalation reaction and preliminary characterizations of a presumably stage‐1 phase IBi2Sr1.8Ca1.2Cu2Ox.
