1-[2-(4-Isobutyl-phen-yl)propano-yl]thiosemicarbazide.

In the title compound, C(14)H(21)N(3)OS, inter-molecular N-H⋯O inter-actions generate ten-membered rings with R(2) (2)(10) ring motifs, whereas N-H⋯S inter-actions generate eight, 14- and 16-membered rings with R(2) (2)(8), R(4) (4)(14) and R(4) (4)(16) ring motifs, respectively. There are weak intra-molecular N-H⋯π inter-actions which might influence the conformation of the mol-ecule. The compound has a stereogenic center but the space group is centrosymmetic so the mol-ecule exists as a racemate.
