Abstract
The asymmetric unit of the title compound, C8H15N3S, contains two independent molecules. In both molecules, the seven-membered cycloheptane ring adopts a chair conformation. An intramolecular N—H...N hydrogen bond is observed in both molecules, forming S(5) graph-set motifs. In the crystal, the two independent molecules are connected through N—H...S hydrogen bonds, forming dimers which are in turn further connected by N—H...S hydrogen bonds into chains along [010].

Summary
Thiosemicarbazones constitute an important class of N,S-donor ligands and their coordination chemistry was initially explored in the early 1960 s (Gingras et al, 1961; Ali & Livingstone, 1974; Lobana et al, 2009) Thiocarbazones and their metal complexes have received considerable research interest owing to their medicinal properties, such as antifungal (Arjmand et al, 2007), anticancer (Sharma et al, 2006), antibacterial (Singh et al, 2008), antiviral (Padmanabhan et al, 2017) and antimalarial (Oliveira et al, 2008). Pairs of molecules form dimers (Fig. 2) through N—HÁ Á ÁS hydrogen bonds, forming an R22(8) graph-set motif
