ONIUM SALT在英语中的意思是什么？

ium化合物

Onium compound

在化学中，鎓化合物或鎓离子是通过质子化阳离子，硫族元素或卤素的单核母体氢化物而正式获得的阳离子。 最古老的鎓离子和同类别的是铵，NH + 4，氨的质子化衍生物NH 3。名称也用于由这些离子中的氢原子取代产生的阳离子 其他基团，如有机基团或卤素; 如四苯基鏻，4P +。 取代基可以是二价或三价的，产生离子如亚铵和腈。 鎓离子的电荷为+1。 具有两个或更多个鎓离子亚类的分子被认为是双离子，三重离子等。 鎓阳离子和一些其它负离子的化合物被称为鎓盐。 ium化合物与复合物相反。 当中心原子获得一个键并成为阳离子时，路易斯碱形成鎓离子。 当中心原子增加一个键并变成负离子时，路易斯酸形成离子。

In chemistry, an onium compound, or onium ion, is a cation formally obtained by the protonation of mononuclear parent hydride of a pnictogen, chalcogen, or halogen. The oldest-known onium ion, and the namesake for the class, is ammonium, NH+ 4, the protonated derivative of ammonia, NH 3. The name onium is also used for cations that would result from the substitution of hydrogen atoms in those ions by other groups, such as organic radicals, or halogens; such as tetraphenylphosphonium, 4P+. The substituent groups may be di- or trivalent, yielding ions such as iminium and nitrilium. Onium ions have a charge of +1. A molecule with two or more onium ion subgroups is said to be a double onium ion, triple onium ion, and so on. Compounds of an onium cation and some other negative ion are known as onium salts. Onium compounds are inversely analogous to ate complexes. Lewis bases form onium ions when the central atom gains one more bond and becomes a positive cation. Lewis acids form -ate ions when the central atom gains one more bond and becomes a negative anion.
