Abstract

A general review and description is given of vacancy patterns in oxygen-deficient perovskites A_mB_mO_3m-x. Thirteen compounds that contain unique oxygen vacancy patterns and that adopt structures related to cubic closest packing are examined in detail: m = 2, x = 1, Ca₂Mn₂O₅, LaSrCuGaO₅, La₂Ni₂O₅, LaSrCuAlO₅, YBaCuFeO₅, Ca₂Co₂O₅; m = 3, x = 1, 2, or 3, LaBa₂-Cu₂TaO₈;, LaSr₂Fe₃O₈, YBa₂Cu₃O₇, LnSr₂Cu₂GaO₇, YBa₂Cu₃O₆; m = 4, x = 1, Ba₂La₂Cu₂Sn₂O₁₁ and Ca₄Ti₂Fe₂O₁₁. The structural similarity among the compounds is stressed by the presentation and examination of AO_3-x slices. The influence of the A and B cations on the manner in which successive AO_3-x layers are stacked is presented and discussed.
