(Received 13 April 2008; accepted 30 April 2008; online 7 May 2008)

The title compound, C₁₀H₁₃N₃S₂, was obtained from a condensation reaction of methyl dithiocarbazate and 4-aminoacetophenone. In the crystal structure, the nearly planar molecule assumes an E configuration, the benzene ring and dithiocarbazate group being located on opposite sides of the N=C bond. C—H⋯π interactions and N—H⋯S hydrogen bonding are present in the crystal structure.

Comment top

As some phenylhydrazone derivatives have been shown to be potential DNA-damaging or mutagenic agents (Okabe et al., 1993), a series of new phenylhydrazone derivatives has been synthesized in our laboratory in past years, and several crystal structures of phenylhydrazone compounds have been determined by X-ray diffraction in order to research their structure-bioactivity relationship (Shan et al., 2003). Recent investigation discovered that sulfur-containing hydrazone compounds are benefit to promote the bioactivities of hydrazone (Jiang, 2007). As part of our ongoing investigation on hydrazone compounds, the title compound with dithiocarbazate component has recently been prepared and its crystal structure is reported here.

The structure of the title compound is shown in Fig. 1. The N2—C7 bond distance of 1.281 (3) Å indicates a typical C=N double bond. The molecule adopts an E configuration about the C=N double bond. The molecule has a nearly planar structure. The C8 atom is well co-planar with the benzene ring with a small atomic deviation of 0.028 (4) Å from the phenylmethylene mean plane. The dithiocarbazate moiety is slightly twisted to the phenylmethylene plane with a dihedral angle of 13.4 (1)°. The shorter N3—C9 bond distance of 1.345 (3) Å implies the N3 atom involved in the electron delocalization in the dithiocarbazate moiety.

It is notable that the N3—C9—S1 bond angle of 113.26 (15)° is much smaller than 120° expected for a sp² hybrid C atom and also much smaller than the corresponding N3—C9—S2 bond angle of 121.66 (16)°, which is similar to that found in related structures reported previously (Shan et al., 2006; Zhang et al., 2005).

Intermolecular C—H···π interaction is observed between C10-methyl group and the benzene ring of the adjacent molecule (Fig. 2), C10—H10a—Cgⁱ angle being 134° and C10···Cgⁱ and H10a···Cgⁱ separations being 3.538 (3) and 2.80 Å, respectively [where Cg is the centroid of the benzene ring and symmetry code (i) = 1 - x,1 - y,1 - z]. Molecules are also linked by intermolecular C—H···S hydrogen bonding (Table 1) to form the supra-molecular chain.

Experimental top

Methyl dithiocarbazate was synthesized in the manner reported previously (Hu et al., 2001). Methyl dithiocarbazate (1.24 g, 10 mmol) and 4-aminoacetophenone (1.35 g, 10 mmol) were dissolved in ethanol (10 ml) and refluxed for 6 h. Yellow crystalline product appeared after cooling to room temperature. They were separated and washed with cold water three times. Single crystals of the title compound were obtained by recrystallization from a 2-propanol solution.

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.
