Extraction and theoretical study on complexation of the strontium cation with antamanide

Popis výsledku v původním jazyce

By using extraction experiments and gamma-activity measurements, the extraction constant corresponding to the equilibrium Sr2+(aq) + 2A(-)(aq) + 1(nb) a double dagger" 1 center dot Sr2+(nb) + 2A(-)(nb) occurring in the two-phase water-nitrobenzene system(A(-) = picrate, 1 = antamanide; aq = aqueous phase, nb = nitrobenzene phase) was determined as log K (ex) (1 center dot Sr2+, 2A(-)) = -0.3 +/- A 0.1. Further, the stability constant of the 1 center dot Sr2+ complex in nitrobenzene saturated with waterwas calculated for a temperature of 25 A degrees C: log beta (nb) (1 center dot Sr2+) = 8.8 +/- A 0.1. Finally, applying quantum mechanical density functional level of theory calculations, the most probable structure of the cationic complex species 1 center dot Sr2+ was derived. In the resulting complex, the "central" cation Sr2+ is bound by six bond interactions to the corresponding six oxygen atoms of the parent ligand 1. The interaction energy of the considered 1 center dot Sr2+ comp
