The divanadates M(2)V(2)O(7) of a virtually unreducible and unoxidizable cation, Mg(2+), of a reducible cation, Cu(2+), and of an oxidizable cation, Mn(2+), have been prepared and characterized by X-ray diffraction, surface area measurements, skeletal IR and UV-vis-NIR spectroscopies, and DTA-TG analyses. These materials have also been tested...
