One dimensional infinite water wires incorporated in isostructural organic crystalline supermolecules with zwitterionic channels

Three isostructures [C16H8O4 center dot 2(CH6N3)center dot 4(H2O)] (1), [C16H10O4 center dot 2(CH6N3)center dot 4(H2O)] (2) and [C14H8N2O4 center dot 2(CH6N3)center dot 4(H2O)] (3) were prepared by the complexation of guanidinium with 4,4'-(ethyne-1,2-diyl)dibenzoic acid, 4,4'-(ethene-1,2-diyl)dibenzoic acid and 4,4'-(diazene-1,2-diyl)dibenzoic acid, respectively. The strong charge-assisted N+-H center dot center dot center dot O- hydrogen bonds cause the assembly of guanidinium and these different acids following almost the same procedure. The hydrogen-bonded water wire is incorporated in zwitterionic channels of organic salts.
