The title compound, C9H8N4S·C3H7NO, adopts an E configuration about both the C=N and C—N bonds. Inter­molecular N—H⋯O hydrogen bonding links the compound to the DMF solvent molecule. The crystal packing is characterized by chains of mol­ecules linked by inter­molecular N—H⋯S hydrogen-bonding inter­actions.

Comment top

The antiproliferative activity of a series of thiosemicarbazones has been reported (Lovejoy & Richardson, 2002). As a research on thiosemicarbazones, the synthesis and crystal structure of a new Schiff base compound derived from thiosemicarbazide and 3-cyanobenzaldehyde has been presented in this article. The crystal structure of 4-cyanobenzaldehyde thiosemicarbazone which is closely related to the title compound has been reported recently (Wu et al. 2009).

The thiosemicarbazone moiety in the title compound (Fig. 1) is nearly planar and shows an E configuration about both the C9—N3 and C8N2 bonds. The C—S bond distance of 1.680 (2) Å agrees well with similar bonds in related compounds, being intermediate between 1.82 Å for a C—S single bond and 1.56 Å for a CS double bond (Sutton et al. 1965). All the bond distances except for the C6—C9 (bond length, 1.448 (3) Å) fall within the normal range. The intermolecular N—H···O hydrogen bond stabilizes the molecular conformation. In the crystal packing, adjacent molecules are linked by N—H···S hydrogen bonds (Table 1 and Fig. 2) to form chains running parallel to the a axis. Weak interactions of the type C—H···O are also present in the structure.

Experimental top

The title compound was synthesized by refluxing 3-cyanobenzaldehyde (2.1 g, 16 mmol) and thiosemicarbazide (1.46 g, 16 mmol) in absolute ethanol (50 ml) for 10 h. After cooling to room temperature, the white solid formed was isolated and dried under vacuum. The title compound was isolated using column chromatography (petroleum ether: ethyl acetate-2:1). Single crystals suitable for X-ray diffraction analysis were obtained from slow evaporation of DMF solution.

Refinement top

H atoms were placed in calculated positions and refined using a riding model, with N—H = 0.86 Å, C—H = 0.93–0.96 Å and with Uiso(H) = 1.2 and 1.5 times Ueq of nonmethyl and methyl type H-atoms.

Special details top

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.
