Abstract: In the title compound, C15H20N2O6S, the C-SO2-NH-C torsion angle is 64.54 (14)°. In the molecule, there is a bifurcated N-H(O,O) hydrogen bond, forming S(7) rings. In the crystal, inversion dimers are formed via O-HO hydrogen bonds involving the carboxyl group, so forming R22(8) rings. These dimers are further linked via pairs of C-HO hydrogen bonds, forming a C(6) chain propagating along the c-axis direction.
