The molecular structure of 4,4'-dimethoxy chalcone single crystal has been determined by X-ray diffraction method. The crystals are orthorhombie with space group P2₁2₁2₁ and a=5.268(3), b=30.639(8), c=8.652(4)Å, Z=4, V=1396.56Å³ and Dx=1.276g/cm³.The structure was solved by direct mothods and refined by full metrix least squares method to the final R=0.082 for 991 reflections having I≥3σ(I). Being irradiated by 1064nm Nd³⁺:YIG laser beam 4,4'-dimethoxy chalcone crystal produces a light of 532 nm wavelength.
