摘要
[GRAPHICS] The crystalline donor-acceptor hydrogen-bonding complexes between 2,5-dichloro-3,6-dihydroxy-1,4-benzoquinone (chloranilic acid) and dipyridylacetylenes (DPA) [2,2'-DPA, 3,3'-DPA, and 4,4'-DPA] were prepared, and crystal structures were revealed by X-ray analysis. The structures of the complexes are formed by intermolecular hydrogen-bonding interactions and demonstrate three supramolecular architectures based on a new common supramolecular synthon, which allows the formation of a different stacking arrangement and ionicity.
