چکیده
In the title compound, C(11)H(11)NOS(2), the benzine ring is coplanar with the thia-zole ring, making a dihedral angle of 0.81 (1)°. In the crystal, adjacent mol-ecules are connected into a helical chain along the b axis by S⋯S contacts [3.4345 (18) Å]. These helical chains are further assembled into a three-dimensional supermolecular network by inter-molecular C-H⋯O hydrogen bond between aromatic ring H atoms and carbonyl groups.
