摘要：
A receptor for carboxylic acids which combines an oxyanion-hole structure with electrostatic forces has been prepared. X-ray diffraction studies have been carried out to evaluate the geometry of both the free receptor and its associated species with several carboxylic acids and many different arrangements have been discovered for the H-bond pattern in the associated species.
