Abstract

Previously studied disubstituted 4,13-diaza-18-crown-6 derivatives, R < N18N > R, in which the substituents were cyanomethyl or propargyl did not show intramolecular, lariat-type cation solvation. The ring-bound cation in the propargyl derivative is solvated by the six macroring heteroatoms and apically by a bifurcated interaction of the type F···K+···F. In contrast, when the sidearm is cyanoethyl, an extended intermolecular network forms when the bound cation is either Na+ or K+.
