There are two independent molecules in the asymmetric unit
of the title compound, C12H9ClN2OS, a Schiff base derived
from hydrazide, in which the dihedral angles between the
thiophene and benzene rings are 3.6 (3) and 7.3 (3). In the
crystal, the two independent molecules are arranged about an
approximate non-crystallographic inversion center and are
connected by two N—H  O hydrogen bonds. Weak C—
H  Cl contacts are also present. Conversely, there are neither
significant aromatic stacking interactions nor contacts involving
S atoms.
