In the process of searching for the phases of the Ag-Ba-Ca-Cu-O system at 1200 ° C under 5 GPa, we found the new oxycarbonate superconductors (Cuo.5Co.5) Ba2Can \_ ~CunO2~ + 3. Two members of the series with n = 3 and n = 4 were isolated as almost single phases; their structures are closely related
