N′-(4-Bromobenzylidene)thiophene-2-carbohydrazide

Abstract

In the title compound, C12H9BrN2OS, the dihedral angle between the aromatic rings is 10.0 (2)°. In the crystal structure, inversion dimers linked by pairs of N—H...O hydrogen bonds occur, generating R22(8) loops. Weak aromatic π–π stacking [centroid–centroid separations = 3.825 (3) and 3.866 (3) Å] also occurs.
