چکیده
In the title Schiff base compound, C(17)H(22)N(2)O(2)S(2), which adopts an E configuration with respect to the imine C=N double bond, the C=N and N-C bond distances are 1.2789 (16) and 1.4546 (16) Å, respectively. In the mol-ecule there are intra-molecular O-H⋯N and N-H⋯S hydrogen bonds, and the CH=N-C substituent is almost coplanar with the benzene ring [C-N-C-C torsion angle = -178.80 (11)°]. The crystal packing is stabilized by inter-molecular C-H⋯O and C-H⋯π inter-actions involving the aromatic ring.
