A new reagent for the highly selective extraction of cesium (e-1,7′–2,2′)4,8′–8,4′-(bis-μ-o-phenylene)bisdicarbollidocobalt(1−)ate, [(C2B9H9)2(C6H4)2Co], abbreviated as BISPHECOSAN is described in this paper. The choice of organic solvent and solubilizer, dependence of distribution ratio of Cs+ on acidity and other parameters are studied. The extraction mechanism based on selective binding of Cs+ cation between two phenylene rings is presented and factors influencing the chemical stability of the reagent are determined.
