Experimental and theoretical study on the complexation of the strontium cation with nonactin
Original language description
From extraction experiments and ?-activity measurements, the extraction constant corresponding to the equilibrium Sr2+(aq) + 2A- (aq) + 1(nb) reversible arrow 1.Sr2+ (nb) + 2A- (nb) taking place in the two-phase waternitrobenzene system (A- = picrate, 1= nonactin; aq = aqueous phase, nb = nitrobenzene phase) was evaluated as log Kex(1.Sr2+, 2A-) = -2.0 0.1. Further, the stability constant of the 1.Sr2+ complex in nitrobenzene saturated with water was calculated for a temperature of 25 C: log ?nb (1.Sr2+) = 7.1 0.1. Finally, by using DFT calculations, the most probable structure of the cationic complex species 1.Sr2+ was derived. In the resulting complex having S4 symmetry, the "central" cation Sr2+ is bound by eight relatively strong bond interactionsto eight oxygen atoms of the parent nonactin ligand 1.
