In the title compound, C10H11N3O2S, the 1,3-benzodioxole and hydrazinecarbothioamide fragments are nearly planar [(mean deviations from planarity for non-H atoms of 0.0325 (12) Å and 0.0707 (10) Å, respectively] and subtend a dihedral angle of 29.06 (5)°. In the crystal, molecules are linked by pairs of almost linear N—H⋯S hydrogen bonds, forming inversion dimers. These dimers are additionally connected by weaker and strongly bent N—H⋯S interactions into chains along [101]. There is one additional weak N—H⋯O contact which, if considered as an interaction, leads to the formation of a three-dimensional network.

All starting materials are commercially available and were used without further purification. The synthesis was adapted from a procedure reported previously (de Oliveira et al., 2012). The hydrochloric acid catalyzed reaction of 3',4'-(methylenedioxy)acetophenone (10 mmol) and thiosemicarbazide (10 mmol) in a 3:1 mixture of ethanol and water (100 ml) was refluxed for 6 h. After cooling and filtering crystals suitable for X-ray diffraction were obtained.
Elemental analysis: Calc. 50.62% for C, 4.67% for H, 17.71% for N and 13.51% for S; found 50.72% for C, 4.66% for H, 17.70% for N and 13.47% for S. The melting point was determined by
to 187° C and the of fusion amount to 25.9 kJ/mol. After melting the compound decomposes.All H atoms were located in a Fourier map. C-bonded H atoms were then geometrically placed (C—H = 0.95–0.99 Å) and refined as riding with Uiso(H) = 1.2Ueq(C(CH), C(CH2)) or 1.5Ueq(C) and AFIX 136 for the methyl group. The N-bonded H atoms were only adjusted to N—H = 0.88 Å and were then refined as riding with Uiso(H) = 1.2 Ueq(N).
Thiosemicarbazone derivatives have a wide range of pharmacological properties. For example, 3',4'-(methylenedioxy)acetophenone thiosemicarbazone derivatives show cytotoxic activity against KB cells (Silva et al., 1998). As part of our study on the synthesis of thiosemicarbazone derivatives, we report herein the
of a new 3',4'-(methylenedioxy)acetophenone thiosemicarbazone derivative.In the
of the title compound, C10H11N3O2S, the molecules are twisted and consists of two nearly planar parts, a benzo[1,3]dioxole fragment and a hydrazinecarbothioamide fragment (mean deviations from planarity for non-H atoms 0.0325 (12) Å and 0.0707 (10) Å, respectively), which subtend a dihedral angle of 29.06 (5)° (Fig. 1). The molecule shows an E conformation for the atoms about the N3—N2 and N2—C1 bonds, which is also observed in the crystal structures of other thiosemicarbazone derivatives (de Oliveira et al., 2012).In the
the molecules are linked by pairs of N—H···S hydrogen bonds into inversion related dimers (Fig. 2 and Table 1). These dimers are further connected by centrosymmetric pairs of weak N—H···S interactions into chains extending along [101] (Fig. 2). Finally, there is one N—H···O contact between that NH2 hydrogen atom which is not involved in N—H···S bonding and the dioxole oxygen O1 (Table 1). If this contact is considered as an interaction the chains are additionally linked into a three-dimensional network (Fig. 2).In the π-π stacking.
the benzo[1,3]dioxole fragments are oriented nearly perpendicular to [001] and are stacked above each other along this direction by the c-glide plane with a repetition period of c/2 = 3.5645 (7) Å implyingFor the adapted synthesis of the title compound, see: de Oliveira et al.

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. |

Thiosemicarbazone derivatives have a wide range of pharmacological properties. For example, 3',4'-(methylenedioxy)acetophenone thiosemicarbazone derivatives show cytotoxic activity against KB cells (Silva et al., 1998). As part of our study on the synthesis of thiosemicarbazone derivatives, we report herein the crystal structure of a new 3',4'-(methylenedioxy)acetophenone thiosemicarbazone derivative.
In the crystal structure of the title compound, C10H11N3O2S, the molecules are twisted and consists of two nearly planar parts, a benzo[1,3]dioxole fragment and a hydrazinecarbothioamide fragment (mean deviations from planarity for non-H atoms 0.0325 (12) Å and 0.0707 (10) Å, respectively), which subtend a dihedral angle of 29.06 (5)° (Fig. 1). The molecule shows an E conformation for the atoms about the N3—N2 and N2—C1 bonds, which is also observed in the crystal structures of other thiosemicarbazone derivatives (de Oliveira et al., 2012).
In the crystal structure the molecules are linked by pairs of N—H···S hydrogen bonds into inversion related dimers (Fig. 2 and Table 1). These dimers are further connected by centrosymmetric pairs of weak N—H···S interactions into chains extending along [101] (Fig. 2). Finally, there is one N—H···O contact between that NH2 hydrogen atom which is not involved in N—H···S bonding and the dioxole oxygen O1 (Table 1). If this contact is considered as an interaction the chains are additionally linked into a three-dimensional network (Fig. 2).
In the crystal structure the benzo[1,3]dioxole fragments are oriented nearly perpendicular to [001] and are stacked above each other along this direction by the c-glide plane with a repetition period of c/2 = 3.5645 (7) Å implying π-π stacking.
