We have successfully intercalated epitaxial iodine spacers between BiO bilayers of the oxide superconductors Bi{sub 2}Sr{sub 2}CuO{sub {ital x}} (Bi 2:2:0:1), Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub {ital x}} (Bi 2:2:1:2), and Bi{sub 2}Sr{sub 2}Ca{sub 2}Cu{sub 3}O{sub {ital x}} (Bi 2:2:2:3), thereby forming new {ital c}-axis-expanded stage-1 superconducting structures. Although the guest iodine layer expands each BiO bilayer by about 3.6 A for all three compounds, the materials remain bulk superconductors with transition temperatures {ital T}{sub {ital c}} as high as 100 K. The respective shifts in {ital T}{sub {ital c}} upon intercalation of the different materials allow examination of the superconductivity mechanism in terms of the role of interplanar and intraplanar Cu-O coupling.
