چکیده
In the title compound, C(15)H(14)N(2)O(2)S, the five-membered ring adopts an envelope conformation and the two hydr-oxy groups lie on opposite sides of the ring. The six-membered rings are oriented at a dihedral angle of 22.63 (3)°. In the crystal structure, inter-molecular O-H⋯S and O-H⋯O hydrogen bonds link the mol-ecules into a two-dimensional network.
