Abstract
In the title molecule, C15H18N2OS, a small twist is noted, with the dihedral angle between the central carbohydrazone residue (r.m.s. deviation = 0.029 angstrom)and the thiophene ring being 12.47 (10)degrees. The syn arrangement of the amide H and carbonyl O atoms allows for the formation of centrosymmetric dimers via N-H center dot center dot center dot O hydrogen bonds. These are linked in the three-dimensional structure by C-H center dot center dot center dot pi interactions. The thiophene ring is disordered over two co-planar orientations, the major component having a site-occupancy factor of 0.833 (2).
