Ammonium hexadeca-oxo-heptavanadate microsquares. A new member in the family of the V₇O₁₆ mixed-valence nanostructures

Abstract

This paper presents the new mixed valence heptavanadate (NH₄)₂V₇O₁₆ micro squares, a further but carbonless member of the vanadium oxide nanotubes and nanourchins family, where ammonium ions replace the long carbon chain amines.
