Synthesis, properties and X-Ray analysis of the new bis(azacrown ethers), containing bridging ureid fragments, are
described. These substances have in their molecule structure both centers of anion linking (proton donating NH groups)
and centers of cation linking (crown ether units) and thus may be considered as potential ion-pare receptors.
