【摘要】 <正> 穴状杂多阴离子[KAs4W40O40]27-的某些衍生物具有抗艾滋病毒活性,这促使我们研究了[KAs4W40O140]27-的各种衍生物.本文报道了[KAs4W40O140]n-(M=Mn2+,Co2+,Ni2+,Cu2+,Cr3+)杂多阴离子在有机溶剂中的反应, 1 实验部分 1.1 仪器和试剂 Varian E-4电子自旋共振仪,Cary 14光谱仪,Bruker WM300核磁
【Abstract】 The reaction of[KAstW10O110(M·H2O)]n(M=Mn2+,Co2+,Ni2+,Co2+ or C43+)anions in toluene is reported.The coordinated water molecules of the title anions can not be substituted by SCN-,Py in aqueous solution.However,she same replacement reaction takes easily in toluene.Some of the title anions can lose the coordinated water molecules directly leading to coordmatively unsaturated site on the surface of the anions in toluene.Synthesis and oxidation properly of the high oxidation state complexes are also reported.
