Synthesis and redox property of transition element tribasic heroply compounds with Mn as the central atom

用直接法合成了以锰为中心原子的过渡元素和钨的三元杂多配合物,经ICP和TG曲线确定其化学式为K5,6[MnM(OH2)W11O39]·xH2O(M=Mn2+,Fe3+,Co2+,Ni2+,Cu2+,Zn2+和Cd2+),采用IR,UV,XRD和XPS等手段对配合物结构进行了表征,用循环伏安测定了其系列配合物的氧化还原性质,得出系列配合物的氧化性顺序,同时讨论配合物的热稳定性.

The transition element tribasic heteropoly compounds with Mn as the central atom had been synthesized directly and characterized by IR,UV,XRD and XPS.By means of ICP and TG,the molecular formulas were confirmed as K_(5,6)·xH_2O(MMn^(2+),Fe^(3+),Co^(2+),Ni^(2+),Cu^(2+),Zn^(2+),Cd^(2+)).Through the determination of cyclic voltammetry,their redox properties were studied.From result,we can know the order of the oxidation of the serial compound.Furthermore,their thermalstabilities were discussed.
