Pb(Ba,Sr)2(Ln,Ca)Cu3Oy (Pb2212, y=7.0-8.4) and Pb(Ba,Sr)2(Ln,Ce)2Cu3Oy (Pb2222, y=9.0-10.4) were synthesized, and crystal structure, phase transition and superconductivity were studied. The lanthanoid contraction was clearly observed in a relationship of 4f-electron number of Ln3+ versus cell volume of Pb2212, consistent with constant oxygen content for all of the lanthanoid substitutions. Transition temperature from oxygen rich phase to poor one was almost constant to be 580°C, in contrast to variation of the ortho-tetra transition temperature in Ba2LnCu3Oy.
