| Abstract: | The title compound (C23H27FeNO4) has been synthesized by the reaction of formylferrocene, ethyl acetoacetate and urea on the surface of SiO2 under microwave irradiation without solvent, and its structure was characterized by elemental analysis, IR, 1H NMR and X-ray single-crystal diffraction analysis. The crystal belongs to triclinic system, space group P?with a = 7.462(2), b = 8.3574(13), c = 16.491(3) ? a = 78.36(2), b = 88.76(3), g = 86.11(2), Mr = 437.32, V = 1004.9(3) 3, Z = 2, Dc = 1.445 g/cm3, m(MoKa) = 7.80 cm-1 and F(000) = 460.00. The structure was solved by direct methods and refined by full-matrix least-squares techniques to the final R = 0.063 and wR = 0.180。 |
