In copper oxide superconductor materials the internal charge transference between the superconducting planes of CuO₂ and the charge reservoir blocks, it is a key factor that controls the superconducting critical temperature. The superconducting planes of CuO₂ are not planes in a strict sense, the position of the Cu(2) atom and the O(2) and O(3) oxygen atoms are not lying in a same plane, the change of its positions are closely related to atomic replacements in the superconducting planes of CuO₂ or in the charge reservoir blocks. Therefore, we correlates the substitutions effects in the canonical unit cell of YBa₂Cu₃O₇ with regard to length and angle bond variation of copper and oxygen atoms with the superconducting critical temperature obtained by Rietveld refinement of X-ray diffraction patterns in polycrystalline powder samples, such as: SmBa₂Cu₃O₇, [Y0,90,Pr0,10]Ba₂Cu₃O₇, [Ca,La]Ba₂Cu₃O₇ and YBa₂Cu₃O₇.

Keywords : Copper oxide superconducting materials; superconducting planes of CuO₂; Rietveld method.
