title: Ethyl 3-[2-(p-tolyl-carbamothio-yl)hydrazinyl-idene]butano-ate.
abstract: The title compound, C(14)H(19)N(3)O(2)S, was obtained from a condensation reaction of N-(p-tol-yl)hydrazinecarbothio-amide and ethyl acetoacetate. The mol-ecule assumes an E configuration; the thio-semicarbazide and ester groups are located on the opposite sides of the C=N bond. The almost planar thio-semicarbazide unit (r.m.s. deviation = 0.0130 Å) is tilted at a dihedral angle of 49.54 (12)° with respect to the benzene ring. Inter-molecular N-H⋯N and N-H⋯S hydrogen bonding stabilizes the crystal structure. The eth-oxy group of the ester unit is disordered over two positions, with a site-occupancy ratio of 0.680 (10):0.320 (10).
