Title: New structural and electrical data on Bi-Mo mixed oxides with a structure based on [Bi{sub 12}O{sub 14}]{sub {infinity}} columns

Abstract

The authors recently described a new family of oxide anion conductors with a structure based on [Bi{sub 12}O{sub 14}]{sub {infinity}} columns (Journal of Solid State Chemistry 122, 394 (1996)). The parent compound of this series can be formulated as Bi{sub 26}Mo{sub 10}O{sub 69} and formation of a solid solution, in the Bi{sub 2}O{sub 3}-MoO{sub 3} binary system, in the range 2.57 {le} Bi/Mo {le} 2.77 was established. The stoichiometry of this series was questioned by R. Enjalbert et al. (Journal of Solid State Chemistry 131, 236 (1997)), but confirmed by D.J. Buttrey et al. (Materials Research Bulletin 32, 947 (1997)). The first part of this paper is devoted to a refutation of criticisms by R. Enjalbert et al. In the second part, a comparison with other Bi{sub 2}O{sub 3}-based oxide anion conductors enables the authors to propose an iono-covalent description of this novel structure type, taking into account all the structural and electrical features, especially new neutron powder diffraction refinement and conductivity measurements under variable oxygen partial pressures.
