钒酰离子
钒酰离子又称氧钒(IV)离子,化学式VO2+,[1]是钒的配位化学中常见的官能团。含有钒酰离子的配合物通常具有蓝色和顺磁性。钒酰离子中的V4+和O2-之间有一个三键。[2]
天然存在
矿物
Cavansite和pentagonite都是含有钒酰离子的矿物。
水
VO2+通常与钠离子配对(NaH2VO4),是海水中第二丰富的过渡金属,仅次于钼。[3]钒酰离子在海洋中的平均浓度为30 nM。某些矿泉水泉也含有高浓度的钒酰离子,如富士山附近的泉水每升通常含有多达54 μg的钒酰离子。 [3]
含有钒酰离子的化合物
- 乙酰丙酮氧钒(IV)(VO(acac)2)
- 硝酸钒酰(VO(NO3)3)[4]
