Abstract

The system Bi2(n+2)Mo n O6(n+1) is described with the superspace formalism. Considering the cationic distribution of the member with n=3, a superspace model is constructed beginning with a model previously proposed for the compound Bi2MoO6. The description of even members requires additional modifications. As a result, two superspace models are proposed for the different members of this system, depending on the parity of the parameter n. Both models have been checked through the Rietveld method combining synchrotron and neutron powder diffraction data.
