CRYSTAL STRUCTURE OF 4,4'-DIMETHOXY CHALCONE
Abstract:
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.
