摘要

A new oxide, Bib>14b>Srb>21b>Feb>12b>Ob>61,b> with a layered structure derived from the 2212 modulated type structure Bib>2b>Srb>3b>Feb>2b>Ob>9b>, was isolated. It crystallizes in the I2 space group, with the following parameters: a=16.58(3)a, shifted with respect to each other and interconnected by means of [Bib>4b>Srb>6b>Feb>2b>Ob>16b>] slices. The latter are the place of numerous defects like iron or strontium for bismuth substitution; they can be correlated to intergrowth defects with other members of the family.
