New hydrogen-bonded donor-acceptor pairs between dipyridylacetylenes and 2,5-dichloro-3,6-dihydroxyl-1,4-benzoquinone

Abstract

[structure: see text] 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… (More)
