This research was undertaken to determine whether by powder diffraction substitution in the "123"-type high Tc oxides, Ln1-xMxBa2-yMyCu3-zMzO6.5+δ (where Ln = lanthanoid, Mx = Me3+, My = Me3+ and Mz = Me3+ and Me2+) could be detected unequivocally. Numerous X-ray and a few neutron powder diffractograms were calculated for substituted compounds. Reflections most sensitive to substitution and the influence of site occupancy for Cu and O atoms are also characterized. The results are compared with some experimental data reported in the literature.
