چکیده
In the title compound, C(13)H(10)ClNO(4)S, the dihedral angle between the aromatic ring planes is 87.07 (6)° and an intra-molecular C-H⋯O inter-action occurs. In the crystal, inversion dimers linked by two O-H⋯O hydrogen bonds arise from the carboxyl groups. N-H⋯O hydrogen bonds link the dimers into chains and short C-Cl⋯π and S-O⋯π contacts are also seen.

In the crystal structure of the title compound, C(11)H(15)NO(4)S, two independent mol-ecules are present per asymmetric unit; they are dimerized through O-H⋯O hydrogen bonds between their carb-oxy groups to generate R(2) (2)(8) loops. An intra-molecular N-H⋯O link in one of the mol-ecules closes an S(5) ring. The dimers are linked by N-H⋯O and C-H⋯O hydrogen bonds to form a three-dimensional ne...
