Lithium ionophore VIII as an extraordinarily effective receptor for the strontium cation: Experimental and theoretical study
Original language description
From extraction experiments and gamma-activity measurements, the extraction constant corresponding to the equilibrium Sr2+(aq) + 2A(-)(aq) + 1(nb) <=> 1 center dot Sr2+(nb) + 2A(-)(nb) taking place in the two-phase water-nitrobenzene system (A(-) = picrate, 1 = lithium ionophore VIII; aq = aqueous phase, nb = nitrobenzene phase) was evaluated as logK(ex) (1 center dot Sr2+, 2A(-)) = 7.8 +/- 0.1. Further, the extremely high stability constant of the 1-Sr2+ complex in nitrobenzene saturated with water wascalculated for a temperature of 25 degrees C: log beta(nb) (1 center dot Sr2+) = 16.9 +/- 0.1. Finally, by using OFT calculations, the most probable structure of the cationic complex species 1.Sr2+ was derived. In the resulting complex, the "central" cation Sr' is bound by six very strong bond interactions to the corresponding six oxygen atoms of the parent ligand 1; the interaction energy of this complex was found to be -959.9 kJ/mol.
