摘要：

A new family of bismuth-copper oxides has been characterized by X-ray and electron diffraction techniques. Its structure is built up from the intergrowth, along the b axis, of n "2201"-type slices with a perovskite-related slice; the general formulation is (Bi2+xSr2-xCuO6)n(Sr8-x′Cu6O16+y). Four members were isolated, corresponding to n = 4, 5, 6, and 7; n < 4 and n > 7 members were only observed in an extended defect area. © 1992.
