The effects of different substitutions on (Pbo.5Cdo.5)SrE(Yo.sCao.5)Cu207 have been investigated. For (Pbo.sCdo.5)Sr2(Yl\_:,Cax)Cu207 (0.0<x\_< 1.0), an anomalous variation of lattice constants with x is observed, and a sharp increase in Tc occurs when x increases from 0.4 to 0.5. For (Pbo.sCdo.s)Sr
