(E)-2-[1-(3-Chloro-4-fluoro-phen-yl)ethyl-idene]hydrazinecarbothio-amide.

In the crystal of the title compound, C(9)H(9)ClFN(3)S, the molecules are inter-connected by N-H⋯S and N-H⋯F hydrogen bonds. There are two different N-H⋯S hydrogen bond: the stronger one links mol-ecules into infinite chains along the b axis with graph-set motif C(4), while the weaker N-H⋯S hydrogen bond combines with the previous one into an R(2) (2)(8) network. Moreover, the chains are linked into layers parallel to (102) by weak N-H⋯F hydrogen bonds, which form an R(2) (2)(22) ring motif. In addition, there are also weak π-π inter-actions between the benzene rings of adjacent mol-ecules [centroid-centroid distance = 3.8997†(15)†à ].
