English abstract 1-Furoyl-3,3-diphenylthiourea (FDFT) was synthesized, and characterized by FTIR, 1H and 13C NMR and ab initio X-ray powder structure analysis. FDFT crystallizes in the monoclinic space group P21 with α 12.691(1), b = 6.026(2), c = 11.861(1) Å, β = 117.95(2) and V = 801.5(3) Å3. The crystal structure has been determined from laboratory X-ray powder diffraction data using direct space global optimization strategy (simulated annealing) followed by the Rietveld refinement. The thiourea group makes a dihedral angle of 73.8(6)° with the furoyl group. In the crystal structure, molecules are linked by van der Waals interactions, forming one-dimensional chains along the a axis
