Guanidinium 4-hydroxy-3-carboxybenzenesulfonate

X.-L. Zhang, X.-M. Chen and S. W. Ng

Abstract: The anions of guanidinium 4-hydroxy-3-carboxybenzenesulfonate, CH₆N₃⁺·C₇H₅O₆S^-, are linked into a linear chain by a short O_carboxylO_sulfonate interaction of 2.611 (2) Å; the hydroxyl group is linked intramolecularly to the carbonyl O atom, also by a short hydrogen bond [OO = 2.601 (2) Å]. Adjacent chains are connected into a three-dimensional network structure through hydrogen-bonding interactions with the cation.
