## Modulated structures of the Bi-2212 and Bi-4413 superconductors have been studied using the supercell five times enlarged in the b-direction. Brief comparison have been made of the modulated structures.

The structure of the oxygen-deficient compound 7Bi 2 O 3 •2WO 3 , a fluorite-derivative phase considered a candidate for electronic applications because of its high ionic conductivity, is investigated by singlecrystal X-Ray diffraction employing Ag-Kα radiation (λ = 0.5608 Å) to minimize the effect
A; a ¼ 116:779ð2Þ; b ¼ 96:089ð3Þ; g ¼ 84:000ð3Þ1; R F ¼ 0:033: The disulphate anions are essentially eclipsed. All three structures can be described as dichromate-like, where the alkali cations coordinate oxygens of the isolated disulphate groups in three-dimensional networks. The K-O and Na-O coord
