چکیده
In the mol-ecule of the title compound, C(16)H(17)NO(3), the aromatic rings are oriented at a dihedral angle of 29.25 (8)°. An intra-molecular O-H⋯N hydrogen bond results in the formation of a nearly planar [maximum deviation 0.034 (13) Å] six-membered ring, which is oriented at dihedral angles of 0.91 (1) and 28.91 (12)° with respect to the aromatic rings. The title mol-ecule is a phenol-imine tautomer, as evidenced by C-O, C-N and C-C bond lengths. In the crystal, mol-ecules are linked by inter-molecular C-H⋯O hydrogen bonds that generate C(8) chains.

In the title mol-ecule, C(17)H(16)N(2)O(3)S, the benzothia-zole fragment and the benzene ring form a dihedral angle of 13.8 (4)°, and an intramolecular O-H⋯N hydrogen bond occurs. In the crystal structure, pairs of weak inter-molecular O-H⋯S and C-H⋯(O,O) hydrogen bonds link mol-ecules into centrosymmetric dimers. These dimers are related by translation along the a axis and form stacks via π-π ...

In the asymmetric unit of the title compound, C(17)H(19)NO(3), there are three independent mol-ecules, which are align nearly parallel to each other and adopt the phenol-imine tautomeric form. In each mol-ecule, an intra-molecular O-H⋯N hydrogen bond results in the formation of an S(6) ring motif. The dihedral angles between the aromatic rings in the three independent mol-ecules are 13.55 (2), ...
