过渡金属配合物的合成、晶体结构及电化学性质

Synthesis,Crystal Structure and Electrochemical Properties of the Transition Metal Complexes

采用常规溶液法,通过控制溶液的pH,合成出2种结构新颖的过渡金属配合物,经元素组成分析和ICP确定其化学式为H[{Cr(OOCCH3)2(H2O)}3O]2[CrMo6O24H6]·24H2O(1)和[Cu(OOCCH3)2(H2O)]2.5(2),用X-射线单晶衍射测定其晶体结构表明,化合物1为三斜晶系,P-1空间群,该化合物是由一个Ander-son[CrMo6O24H6]结构和[{Cr(OOCCH3)2(H2O)}3O]通过氢键形成1D结构.化合物2为单斜晶系,C2/c空间群,配合物之间通过氢键形成2D结构.利用IR光谱、UV光谱、TG曲线对所合成的配合物进行了结构表征,化合物1具有很好的电化学和电催化性质.

In this paper,two novel structure of POMS by using hydrosol and control solution pH value are propased.The elements of analysis and ICP determine their patents for H[{Cr（OOCCH3）2（H2O）}3O]2[CrMo6O24H6]·24H2O（1） and [Cu（OOCCH3）2（H2O）]2.5（2）,their crystal frame were confirmed via X-ray single crystal,which show Compound 1 is three inclined crystal department,P-1 space group,the compound is an Anderson [CrMo6O24H6] structure and [{Cr（OOCCH3）2（H2O）}3O] through hydrogen bonds constitute 1D structure.Compound 2 is inclined,C2/c space group,the complexes constitute 2D structure by hydrogen bonds.Using IR spectra,UV absorption spectra,TG curve of synthetic compounds for their structure characterizations,Compound（1） with good electrochemical catalysis properties and metal.
