Abstract A comprehensive review of structure work on high-T c oxides as reported during the years 1987 and 1988 is given. Thirteen structures are refined from X-ray single-crystal and/or neutron powder diffraction data:I. (Ba1−x ,K x )BiO3 (T c =30 K),II. (La2−x , Sr x )CuO4 (T c =40 K),III. (Nd, Ce, Sr)2CuO4 (T c =28 K),IV. (Nd2−x , Ce x )CuO4 (T c =24 K),V. YBa2Cu3O7 (T c =90 K),VI. YBa2Cu4O8 (T c =80 K),VII. Y2Ba4Cu7O14 (T c =40 K),VIII. Pb2Sr2NdCu3O8 (T c =70 K),IX. TlBa2CaCu2O7 (T c =103 K),X. TlBa2Ca2Cu3O9 (T c =120 K),XI. Tl2Ba2CuO6 (T c =90 K),XII. Tl2Ba2CaCu2O8 (T c =112 K),XIII. Tl2Ba2Ca2Cu3O10 (T c =125 K). Except forI (perovskite type),II (K2NiF4 type) andIV (Nd2CuO4 type) they represent new structure types. Structure data, bond distances, structure drawings and calculated X-ray powder diffraction patterns are given for each compound. Structural features and correlations with superconductivity are discussed. The review contains 301 citations.
