In the crystal of the title molecular salt, C7H10N+·C6H5O4S-, the benzenesulfonate units are linked through phenol-sulfonate O-HO hydrogen bonds, forming chains along the c-axis direction. These chains are linked via N-HO hydrogen bonds involving two of the three H atoms of the ammonium group of the 4-methylanilium cation, giving rise to two-dimensional networks parallel to the bc plane which are further connected through an additional N-HO interaction in which the third ammonium H atom is involved, generating a three-dimensional network.
