The title compound, C16H14N4S, has been synthesized by the reaction of pentane-2,4-dione with 5-amino-3-benzylthio-4-cyano-1-H-pyrazole in ethanol, and its crystal structure was determined by X-ray diffraction method. The crystal is of monoclinic, space group P21/n with a = 8.699(3), b = 23.139(9), c = 7.536(3) ? b = 92.400(8), V = 1515.5(10) 3, Z = 4, Mr = 294037, Dc = 1.290 g/cm3, = 0.71073 ? (MoKa) = 0.212 mm-1 and F(000) = 616. The structure was refined to R = 0.0533 and wR = 0.1141 for 2672 unique reflections with Rint = 0.06. The structure is a dimmer linked by intermolecular contact S(1)…HC(8) with the S(1)C(8) distance of 3.875 and the angle of 164.8.
