硝酸氧钒(IV)

硝酸氧钒(IV)是一种无机化合物，化学式为VO(NO3)2。它的浓溶液（25~50%）不稳定，稀溶液（10%）在二氧化碳气氛中的阴凉处稳定。在25%浓度以下时，它按下式分解：Vernazza, E. Decomposition of nitrates and nitrites of metals having several valences. IV. Vanadyl nitrate. Industria Chimica (Rome), 1934. 9: 1616-1623. . .
 6 VO(NO3)2 + 5 H2O → 3 V2O5 + 10 HNO3 + 2 NO
更高浓度下，还有一氧化二氮和二氧化氮生成。它在13%硝酸中于50 °C开始分解，放出一氧化氮。Pogrebnaya, V. L.; Baranov, A. V.; Mal'chikova, T. B.; Larin, V. A.; Bez'yazychnyi, P. I.; Nesterenko, A. I.

CAN78: 102427.它可以在硝酸双氧钒和一氧化氮的反应中生成：Bursa, Stanislaw; Kosmider, Joanna; Straszko, Jerzy; Szaniawska, Daniela.

 3 VO2NO3 + NO + 2 HNO3 → 3 VO(NO3)2 + H2O
