Abstract
Three isostructures [C16H8O4·2(CH6N3)·4(H2O)] (1), [C16H10O4·2(CH6N3)·4(H2O)] (2) and [C14H8N2O4·2(CH6N3)·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⋯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.
