The crystal chemistry of several Ba/sub 2/RCu/sub 3/O/sub 7/ high-T/sub c/ superconductors (R = Y, Pr, Sm, Eu, Gd, Dy, Ho, Er, Tm) has been studied by x-ray diffraction on twinned crystals. All samples except the Pr compound show superconductivity around 90 K. From the variation of the interatomic distances with different rare-earth ions, we infer the presence of a (CuO/sub 2/-BaO-CuOD'Alembertian-BaO-CuO/sub 2/) building unit.
