Je. Redman et al., COOPERATIVE BINDING OF POTASSIUM CATION AND CHLORIDE ANION BY NOVEL RHENIUM(I) BIPYRIDYL AMIDE CROWN-ETHER RECEPTORS, Chemical communications, (2), 1998, pp. 231-232
New rhenium(I) bipyridyl amide crown ether receptors are prepared and
shown to complex K+CI- ion pairs in which crown ether complexation of
the potassium cation cooperates in the binding of chloride anion.
