title: Crystal structure ofN-ethyl-2-(1,2,3,4-tetra-hydro-naphthalen-1-yl-idene)hydrazinecarbo-thio-amide.
abstract: There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C13H17N3S, one of them being disordered over the methyl group [site-occupancy ratio = 0.705 (5):0.295 (5)]. The maximum r.m.s. deviations from the mean plane of the non-H atoms for the tetra-lone fragments amount to 0.4572 (17) and 0.4558 (15) Å. The N-N-C-N fragments are not planar and torsion angles are -9.4 (2) and 8.3 (2)°. In the crystal, the mol-ecules are linked by weak N-H⋯S inter-actions into chains along [100] with graph-set motifC(4) and connected by weak N-H⋯S and C-H⋯S inter-actions, formingR21(10) rings. The Hirshfeld surface analysis indicates that the most important contributions for the crystal packing are the H⋯H (64.20%), H⋯S (12.60%) and H⋯C (12.00%) inter-actions. The crystal packing resembles a herringbone arrangement when viewed along [001].
