✦ Synopsis


The title compound, C~10~H~28~N~2~O~10~S~2~, was synthesized by the reaction of concentrated sulfuric acid with (R,S)-ethambutol. The zwitterionic amino–sulfate system, protonated at both N atoms, lies about a centre of symmetry. The asymmetric unit also contains a solvent water molecule. In the crystal structure, intermolecular O—H...N and N—H...O hydrogen bonds link the molecules into a three-dimensional network.
