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 io...
