摘要：

The structural properties of the perovskite system Ba(Bi1-xLix)O3-y have been investigated for 0.0 < x < 0.25. Over this composition range, the nominal Bi oxidation state varies between +4 and +4.33 and no superconducting propeties were observed. The Li-rich end member of this series, Ba4Bi3LiO11, exhibits a new type of superstructure due to cation order in the octahedral sites-tetragonal P4 mmm, Z = 1, a = 6.101(1), b = 8.628(2)Å. The ordered structure is different from that observed for the analogous Ba4M3LiO12 phases where M = Sb, Nb, Ta, and possible reasons for this are discussed. In particular, the structures of the Sb and Bi phases are compared in detail using Madelung energy calculations. © 1990.
