Abstract

A general review and description is given of vacancy patterns in oxygen-deficient perovskites AmBmO3m-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 AO3-x slices. The influence of the A and B cations on the manner in which successive AO3-x layers are stacked is presented and discussed.
