Abstract:(E) -3- (2- furyl)propenoic acid was synthesized by making use of phase transfer catalysis (PTC) in the existence of potassium acetate and both 2 - furyl methanal and diacetyl oxide as raw material. Its structure characterized by UV, IR and X- ray single crystal diffraction. Molecular formula and formula weight of target compound that synthesized were C7H6O3 and 138.12 respectively. The crystal belongs to monoclinic system and C2/c space group. Unit cell is: a = 18. 993 (6) A, b = 3. 8474 (12) A, c = 20. 095 (6) A, α = 90.00°β = 114. 054° (4), γ = 90.00°, V= 1341.0 (7)nm^3, Z = 8, Dr = 1. 368 Mg/cm^3, F(000) = 576,μ (MoK / a) = 0. 71073. The structure was given by direct method. Final deviate factor was R1 = 0. 0645 and wR2 = 0. 1360. Laminar compound was formed by intermolecular weak interaction.
