A new series of BiPb-cuprates of the formula BiPbSrLnCuO6 (Ln = La, Pr, Nd), which are isotypic with the superconducting Bi-cuprate, Bi2Sr2CuO6+y, has been prepared. The new BiPb-cuprates are nonsuperconducting, but when doped with holes by replacing part of Ln with Sr, superconducting cuprates of the formula BiPbSr1+xLn1-xCuO6 showing a maximum Tc of 25K for Ln = La at x = 0.25 are obtained. Unlike the Bi-cuprates, the parent and the superconducting BiPb-cuprates are free from the structural modulation.
