Abstract
We have synthesized mixed-valence derivatives of the layered oxide HLa Nb2O7, structurally related to perovskite, by chemical reduction, eit her at room temperature or at 650 degrees C. The thermal behavior of t his compound, its structure and change in transport properties upon hi gh temperature doping are discussed. High temperature reduction turns the white insulating precursor into a mixed-valence blue bronze with a layered structure and semi-conducting-like properties.
