The asymmetric unit of the title compound, C8H20N+·C21H26NO3S-, contains two indpendent ion pairs which are disposed about a psuedo-inversion center, generating an ammonium-carboxylate N-HO hydrogen-bonded four-component cluster. In the crystal structure, adjacent clusters are linked by hydroxy-carboxylate O-HO hydrogen bonds, forming a chain.
