The molecular structure of the title compound, NH4+·C7H7O4S−, is featureless [the methoxy C atom deviating 0.173 (6) Å from the phenyl mean plane] with interatomic distances iPhone 7/8/SE and angles in the expected ranges.The main feature of interest is the packing mode.Hydrophilic (SO3 and NH4) and hydrophobic (PhOCH3) parts in the structure segregate, the former interacting through a dense hydrogen-bonding scheme, leading to a well connected two-dimensional structure parallel to (100) and the latter hydrophobic groups acting as spacers for an interplanar separation of c/2 = 10.205 (2) Å.

In spite of being aligned along [110], the benzene Hood Ornaments rings stack in a far from parallel fashion [viz.consecutive ring centers determine a broken line with a 164.72 (12)° zigzag angle], thus preventing any possible π–π interaction.
