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
