氯化钯与4-(2-吡啶偶氮)间苯二酚、硫酸四苯锑形成的离子缔合物的结构与性质研究

Structure and Characterization of Tetraphenyistibonium 4-(2-Pyridylazo) resorcinolate Complex With Palladium Chloride

本文对离子缔合物[(C_6H_5)_4Sb^+,PdCl(C_(11)H_7N_3O_2)^-]进行了制备,经元素分析、红外光谱和核磁共振谱分析,确定了络合物的组成和结构,并测定了其吸收光谱、电导率和稳定常数。考察了络合物在水中的存在状态及其电荷性质,并对其形成机理进行了初探。

Ion association complex, [( C_6H_5)]_4 Sb^+, PdClR^-], formed by 4-(2-pyridylazo)resorcinlo (PAR =H_2R), PdClR^-and tetraphenylstibonium was reported. Its composition and structure were determined by elemental analysis, IR and ~1H-NMR spectra, The value of absorption spectrum, λ_(man)=529nm, and the stability constant, β=5.79×10~4, were also determined byspectrophotometry. The extraction mechanism consists of the formation of an ion-association complex was discussed preliminarily.
