摘要：

Gentle reduction of solid MoO3 leads to four distinct phase of HxMoO3. These compounds have a wide range of colors and crystal classes:phase Ⅰ (0.25< x< 0.40), blue, orthorhombic; phase Ⅱ (0.85< x< 1.04), blue, monoclinic; phase Ⅲ (1.55< x< 1.72), red, monoclinic; and phase Ⅳ (x=2.0), green, monoclinic[1-3]. We have now obtained a new MoO3 phase (NH4)MoO3 with network structure from an aqueous solution of Na2MoO4 reduced by NH2NH2·2HC1 at 170℃.
