Abstract

The synthesis and crystal structure of a new perovskite-based bismuth oxide are reported. The phase, of composition Ba1.7K1.3Bi2O7, is the n=2 member of the Ruddlesden-Popper series An+1BnO3n+1. It has tetragonal symmetry, space group I4/mmm, with unit-cell dimensions a=4.2477(6), and c=21.885(3). The phase is synthesized for the alkali metals K and Rb from KOH (RbOH)+Ba(OH)2 H2O melts. The stoichiometry is apparently not easily varied. The phase is not superconducting down to 2 kelvin.
