(2-Hydroxyethyl)(propyl)azanium 2-[(2-carboxyphenyl)disulfanyl]benzoate monohydrate

Abstract

With the exception of the terminal hydroxy group [N—C—C—O = 53.8 (5)°], the cation of the title salt hydrate, C5H14NO+·C14H9O4S2−.H2O, is a straight chain. A twisted conformation is found for the anion [C—S—S—C = −87.44 (16)°]. In the crystal, the anions self-assemble into a helical supramolecular chain via charge-assisted O—H...Oc hydrogen bonds. These chains are connected into a three-dimensional network via N—H...Oc, N—H...Ow, Oh—H...Ocb, and Ow—H...Oc hydrogen-bonding interactions (c = carboxylate, w = water, h = hydroxy and cb = carbonyl).
