MetadataShow full item record
In the structure of the title compound, C8H12NO+烷H5O6S-爲O, isolated from the reaction of 2-(4-aminophenyl)ethanol with 5-sulfosalicylic acid, the cations form head-to-tail hydrogen-bonded chains through C11(9) anilinium N+-HOhydroxyl interactions while the anions also form parallel but C11(8)-linked chains through carboxylic acid O-HOsulfonate interactions. These chains inter-associate through a number of N+-HO and O-HO bridging interactions, giving a two-dimensional array in the ab plane.
