摘要：

Structural data were obtained by profile refinement of neutron diffraction powder patterns of cuprates. Space group I4/mmm, No. 139: La1.8Ba0.2CuO4, a = 3.8008(3), c = 13.3608(8) angstrom, La1.9Ca0.1CuO4, a = 3.8015(4), c = 13.2176(10) angstrom, La1.8Ca0.2CuO4, a = 3.8013(4), c = 13.2325(9) angstrom, La2Cu0.5Ni0.5O4, a = 3.8512(4), c = 13.0010(12) angstrom. Space group Abma, No. 64: La2Cu0.8Zn0.2O4, a = 5.4041(4), b = 13.1545(6), c = 5.4564(4) angstrom. Space group Pmmm, No. 47: HoSrBaCu3O7, a = 3.8460(6), b = 3.8422(7), c = 11.6727(11) angstrom, NdSrBaCu3O7, a = 3.8935(6), b = 3.8687(5), c = 11.7074(15) angstrom, LaSrBaCu3O7, a = 3.9024(8), b = 3.9067(8), c = 11.7688(19) angstrom, NdCaBaCu3O7, a = 3.8944(3), b = 3.8837(4), c = 11.6559(27) angstrom, LaCaBaCu3O7, a = 3.9076(9), b = 3.8912(8), c = 11.7127(28) angstrom.
