Abstract : Members of the system Fe-Nb-O and Fe-W-O have been compared, and their electronic properties have been correlated with the structural parameters. The compounds crystallize as ordered variants of the basic alpha-PbO2 structure, and the nature of the ordering of the FeO6 and NbO6 or WO6 octahedra determines the conductivity which may be observed for these phases.
