(2E)-N-Methyl-2-[(2E)-3-phenylprop-2-en-1-ylidene]hydrazinecarbothioamide

The title compound, C11H13N3S, is close to being planar, with a dihedral angle of 9.64 (3)° between the benzene ring and the thiosemicarbazone mean plane, maintained by the presence of π-conjugation in the chain linking the the two systems. In the crystal, N—H...S hydrogen bonds form centrosymmetric dimers through a cyclic association [graph-set R22(8)].
