    Abstract

    The crystal structure refinements of Pb2Sr2Tb1-xCaxCu3O8 for x=0.0 and 0.5 was performed as a constrained refinement in space group Pi and bond valency sums for the cations were calculated from the interatomic distances. Ca-doping causes an oxidation of Pb in the PbO layers but no oxidation of Cu in the CuO2 layers was observed. Magnetic susceptibility measurements showed that Pb2Sr2Tb.5Ca.5Cu3O8 was none superconducting down to 15 Kelvin which is in contrast to superconducting Pb2Sr2Y.5Ca.5Cu3O(8).
