Abstract

A novel alluaudite type vanadate has been successfully synthesized in its single crystal and polycrystalline forms. Its crystal structure was determined by means of X ray diffraction measurements. This new vanadate crystallizes in monoclinic system. The crystal structure of this vanadate displays an open transition metals based framework enclosing two kind of tunnels where the sodium cations are located. Moreover, the purity of the obtained powder was confirmed by X ray powder diffraction analysis. Furthermore, this new vanadate was characterized by scanning electron microscopy, Infrared spectroscopy and by magnetic measurements. The magnetic susceptibility showed the antiferromagnetic behavior of this vanadate with negatve Curie- Weiss temperature consistently with the expected magnetic interactions between iron cations.
