摘要：
From extraction experiments in the two-phase water/nitrobenzene system and gamma-activity measurements, the stability constant of the beauvericin center dot A Pb2+ complex species dissolved in nitrobenzene saturated with water was determined. By using quantum mechanical density functional level of theory calculations, the most probable structure of this complex was derived.
