| Abstract: | A new type derivative 4＇-methoxy-7-ethoxyl isoflavone was synthesized by using formononetin as the precursor. The crystal structure of the product was characterized by means of X-ray diffraction, and its electronic structure was then analyzed by conducting quantum chemi- cal calculations. At the same time, the calculations and structure of the product were optimized based on density functional theory （DFT） and B3LYP method. Results indicate that the optimized calculation results agree well with the experimental ones and can be used for calculating frontier molecular orbital and natural charge population of the optimized structure. |
