Four non-superconducting oxides, i.e. LaBa2Cu2TaO8, LaBa2Cu2NbO8, PrBa2Cu2TaO8 and PrBa2Cu2NbO8, were synthesized. Their crystallographic structures were determined by means of the Rietveld analysis using X-ray powder diffraction data. In these compounds, Ta and Nb ions were found to preferentially occupy the Cu 1 site between the two Ba layers in the LaBa2Cu3O7-type structure. The absence of superconductivity in these materials was discussed in terms of the bond valence sum of each cation in the crystal and a possibility to exhibit superconductivity by modifying these materials was suggested.
