2-(1,2,3,4-Tetra­hydro­naphthalen-1-yl­idene)hydrazinecarbothio­amide

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 envelope conformation 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.
