due to the hydrogen-bonded (+)N-H cdots, three dots, centered O system in the oxine adduct of U(VI) have been identified and found to occur in the spectra of several newly prepared U(VI) adducts of oxine derivatives. Interligand steric effects in the U(VI) complexes of most 7-substituted oxines prevent the formation of the 1:3 adduct. Complexes of the type ML(2)X, where X is a small co-ordinating species
在U(VI)的牛加成物中,氢键合(+)NH杂点,三个点,中心O系统引起的红外波段已被鉴定,并发现在几个新制备的U(VI)的牛加成物中的光谱中衍生品。大多数7-取代的oxine的U(VI)配合物中的配位体空间效应阻止了1:3加合物的形成。而是形成了ML(2)X类型的复合物,其中X是溶液中存在的一个小的配位物质。对于2-取代的肟,在2-取代的水和配位的水之间的空间相互作用导致络合物的不稳定和随后随着溶液pH的升高而水解。
