Description
  • The title compound E-2-(4-isopropylbenzylidene)thiosemicarbazone (1) derived from the reaction of 4-isopropylbenzaldehyde and thiosemicarbazide in ethanol solution has been synthesized and characterized by elemental analyses, FT-IR and 1H NMR spectroscopy and single-crystal X-ray diffraction. Its optimized geometry together with the theoretical assignment of the vibrational frequencies of the title compound has been computed by using density functional theory (DFT) method. In the gas phase the four conformers of the title compound were found and it was found that the conformer Sn1 is the most sta ble one. The title compound crystallizes in the monoclinic space group P21/c with unit cell parameters: a = 14.4054(4), b = 5.6832(10), c = 14.4337(3) Å, β = 93.306(2) , V = 179.70(5) Å3 and Z = 4.
