چکیده
The mol-ecule of the title compound, C(16)H(10)N(2)OS, is approximately planar, the dihedral angle between the 1,3-benzothia-zolo[3,2-a]imidazol-3(2H)-one and the benzyl-idene moieties being 4.10 (8)°. A weak intra-molecular C-H⋯S inter-action generates an S(6) ring. No inter-molecular hydrogen bonds are observed in the crystal structure.
