چکیده
The title mol-ecule, C(12)H(10)N(2)O(3)S, is nonplanar with an inter-planar angle of 33.44 (7)° between the benzene and thio-phene rings. In the crystal there exist only weak inter-molecular C-H⋯O inter-actions, π-π inter-actions between the benzene rings [centroid-centroid distance = 3.7465 (14) Å] and X-Y⋯π inter-actions to the thio-phene and benzene rings [N⋯centroid distances = 3.718 (3) and 3.355 (3) Å, respectively]. Inter-molecular C-H⋯O inter-actions link the mol-ecules into chains parallel to the a axis.

In the title compound, C(12)H(10)N(2)O(3)S, the dihedral angle between the benzene and thio-phene rings is 43.17 (4)°. The crystal structure is devoid of any hydrogen-bonding inter-actions. However, π-π inter-actions between the benzene and thio-phene rings [distance between ring centroids = 3.6850 (11) Å] stack the mol-ecules along the a axis. The absolute structure could not be determined as ...
