| 摘要: 本文报道了[KAs4W40O140(M·H2O2]n-杂多阴离子中配位水的取代反应.在水溶液中,许多配体,如[Fe(CN)6]4-、[Fe(CN)6]3-,SO32-等都能取代配位水形成具有特征颜色的配离子.在水溶液中不能发生的配体取代配位水的反应,在非极性有机溶剂中却容易发生,这与配位水分子在非极性有机溶剂中易脱去形成配位不饱和态有关. |

| Abstract: The substitution reaction of coordinated water molecules in the [KAs4W40O140(M·H2O2]n-,anions has been reported.Many ligands,such as[Fe(CN)6]4-,[Fe(CN)6]3-,SO32-are able to substitute the coordinated water molecules in the title anions forming complexes with characteristic colors in aqueous solution.the substitution reactions of ligands not feasible in aqueous solution take place easily in nonpolar solvent,which is related to that of the dissociation of the water molecules coordinated to the "surface" substituted atoms of the polyanion occurs easily,which leads to coordinatively unsaturatcd sites on the surface of the hetcropolyanion. |
