Abstract
Two molecules of cavitand tetracarboxylic acid and four molecules of 2-aminopyrimidine assemble into a capsule via 16 hydrogen bonds, as shown by 1H NMR titration and X-ray crystallographic analysis; in the solid state, two molecules of nitrobenzene are encapsulated in the capsule.Keywords
