The title molecule, C17H18N4S, is not planar, as indicated by the dihedral angle of 27.24 (9)° between the two benzene rings. In the crystal, intermolecular N—H⋯S hydrogen bonds link pairs of molecules into inversion dimers.

Acetophenone (10.0 mmol) and thiocarbohydrazide (5.0 mmol) were mixed in 50 ml flash under sovlent-free condtions After stirring 3 h at 373 K, the resulting mixture was cooled to room temperature, and recrystalized from ethanol, and afforded the title compound as a crystalline solid.
All H atoms were placed in geometrically idealized positions (N—H 0.86 and C—H 0.93–0.96 Å) and treated as riding on their parent atoms, with Uiso(H) = 1.2–1.5Ueq(C,N).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Much interest has recently been paid to the design of schiff base derivatives and complexes, owing to their wide range of biological activities and catalytical abilities (Loncle et al., 2004; Camp et al., 2010). We have synthesized title compound, (I), and report here its crystal structure (Fig. 1). The bond lengths and angles are normal and correspond to those observed in bis(3-fluorophenylmethine)carbonohydrazide (Meyers et al., 1995). The planes of atoms N2/N1/C1 and benzene ring C4-C9 form a dihedral angle of 2.62 (23)°, indicating that this part of the molecule is nearly planar. However, benzene rings C4-C9 and C12-C17 form a dihedral angle of 27.24 (9)°. Intermolecular N—H···S hydrogen bonds link two molecules into one dimer (Table 1, Fig. 2).
