It is shown that the phase YSr2Cu2.aCF0.207 can be made superconducting by substitutions of either Ca at the Y site or Ba at the Sr site. The variation of Tc for Yl-yCaySr2-xBaxCu2.sCro.207 has been determined for a range ofx and y, and the superconducting properties have been correlated with struct
