The actual nuclear and magnetic structures of the oxygen perovskites [Ba 2؊3x Bi 3x؊1 ][Fe 2x Bi 1؊2x ]O 2؉3x/2 (0.40 < x40.50) were studied combining XRPD and NPD data. The incommensurate modulated structures of the members x ‫؍‬ 0.45 and x ‫؍‬ 0.48 were determined in the superspace formalism. It i
