The title compound, [Na(C25H33N2O6S2)(H2O)(2)], was obtained as a product of the reaction of sodium 4-amino-3,5-diethylbenzenesulfonate with acetylacetone in the presence of hydrochloric acid in methanol. The molecule lies on a crystallographic twofold rotation axis and is a 'triple' internal salt which has three positive charge centers and three negative charge centers. The Na atom has a tetrahedral coordination geometry. The O atoms of the sulfonate groups are disordered over two positions with site occupancy factors of 0.87 and 0.13; the methyl groups of the ethyl substituents are disordered equally over two positions.
