Crystal structure of 1-(4-methyl­phen­yl)-3-(propan-2-yl­­idene­amino)­thio­urea

In the title thio­semicarbazone, C11H15N3S, the p-tolyl-N—H and imino-N—H groups are anti and syn, respectively, to the central thione-S atom. This allows for the formation of an intra­molecular p-tolyl-N—H⋯N(imino) hydrogen bond. The mol­ecule is twisted with the dihedral angle between the p-tolyl ring and the non-hydrogen atoms of the N=CMe2 residue being 29.27 (8)°. The crystal packing features supra­molecular layers lying in the bc plane whereby centrosymmetric aggregates sustained by eight-membered thio­amide {⋯HNCS}2 synthons are linked by further N—H⋯S hydrogen bonds. Layers are connected via methyl-C—H⋯π inter­actions. The supra­molecular aggregation was further investigated by an analysis of the Hirshfeld surface and comparison made to related structures.
