The molecular structure of the title compound, C11H13N3S, is not planar: the maximum deviation from the mean plane of the non-H atoms is 0.521 (2) Å for an aliphatic C atom, which corresponds to an for the non-aromatic ring. The hydrazinecarbothioamide substituent and the benzene ring have maximum deviations from the mean planes through the non-H atoms of 0.0288 (16) and 0.0124 (27) Å, respectively, and the dihedral angle between the two planes is 8.84 (13)°. In the crystal, molecules are linked into chains along [1-10] by pairs of N—H⋯S hydrogen bonds between molecules related by centres of symmetry.

All starting materials were commercially available and were used without further purification. The synthesis was adapted from a procedure reported previously (Thanigaimalai et al., 2011). The hydrochloric acid catalyzed reaction of 1-tetralone (10 mmol) and thiosemicarbazide (10 mmol) in a 3:1 mixture of ethanol and water (100 ml) was refluxed for 7 h. After cooling and filtering, crystals suitable for X-ray diffraction were obtained by recrystallization from tetrahydrofurane.
All non-hydrogen atoms were refined anisotropically. C—H H atoms were positioned with idealized geometry and were refined isotropically, with Uiso(H) = 1.2 Ueq(C) using a riding model with C—H = 0.97 Å for aromatic and 0.93 Å for methylene H atoms. N—H H atoms were located in difference map, their bond lengths set to 0.89 Å and finally they were refined isotropically with Uiso(H) = 1.2 Ueq(N) using a riding model.
Thiosemicarbazone derivatives have a wide range of pharmacological properties. For example, ketonethiosemicarbazones show pharmacological activity against melanogenesis in melanoma B16 cells (Thanigaimalai et al., 2011). As part of our study on the synthesis of thiosemicarbazone derivatives, we report herein the
of 2-(3,4-dihydronaphthalen-1(2H)-ylidene)hydrazinecarbothioamide.In the
of the title compound the maximum deviation from the least squares plane through all non-hydrogen atoms is 0.5205 (23) Å for C3, which is in agreement with the observed for the non-aromatic ring (Fig. 1).The molecule shows an
conformation for the atoms about the C1—N1/N1—N2/N2—C11 bonds. The mean deviations from the least squares planes for the N1/N2/C11/N3/S1 and C5/C6/C7/C8/C9/C10 fragments amount to 0.0288 (16) Å for N2 and 0.0124 (27) Å for C7, respectively, and the dihedral angle between the two planes is 8.84 (13)°. The conformation for the thiosemicarbazone fragment is also observed in other structures (Pederzolli et al., 2011 and Bittencourt et al., 2012).The molecules are connected via centrosymmetric pairs of N—H···S hydrogen bonds, forming a one-dimensional H-bonded polymer along [1 -1 0] (Fig. 2 and Table 1).

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, ketonethiosemicarbazones show pharmacological activity against melanogenesis in melanoma B16 cells (Thanigaimalai et al., 2011). As part of our study on the synthesis of thiosemicarbazone derivatives, we report herein the crystal structure of 2-(3,4-dihydronaphthalen-1(2H)-ylidene)hydrazinecarbothioamide.
In the crystal structure of the title compound the maximum deviation from the least squares plane through all non-hydrogen atoms is 0.5205 (23) Å for C3, which is in agreement with the envelope conformation observed for the non-aromatic ring (Fig. 1).
The molecule shows an trans conformation for the atoms about the C1—N1/N1—N2/N2—C11 bonds. The mean deviations from the least squares planes for the N1/N2/C11/N3/S1 and C5/C6/C7/C8/C9/C10 fragments amount to 0.0288 (16) Å for N2 and 0.0124 (27) Å for C7, respectively, and the dihedral angle between the two planes is 8.84 (13)°. The trans conformation for the thiosemicarbazone fragment is also observed in other structures (Pederzolli et al., 2011 and Bittencourt et al., 2012).
The molecules are connected via centrosymmetric pairs of N—H···S hydrogen bonds, forming a one-dimensional H-bonded polymer along [1 -1 0] (Fig. 2 and Table 1).
