The asymmetric unit of the title compound, C10H17N3S, consists of three symmetry-independent mol-ecules with distinctly different conformations, as indicated for example by the C-N-C-C torsion angles of -155.9 (3), 89.9 (3) and 81.1 (4)° along the bond between thio-urea and allyl units. In the crystal, mol-ecules are connected via N-H⋯N and N-H⋯S hydrogen bonds into chains extending along [110]...

In the title compound, C(16)H(17)N(3)S, the amino-thio-urea unit is nearly planar (r.m.s. deviation = 0.0425 Å), and is twisted with respect to the tolyl and phenyl rings by 57.84 (7) and 15.88 (14)°, respectively; the tolyl and phenyl rings are twisted by 65.64 (11)° to each other. Inter-molecular N-H⋯S and weak C-H⋯S hydrogen bonds are present in the crystal structure.
