Synthesis and Crystal Structure of a Chalcone Analog: (2E)-3-(3,4-Dimethoxyphenyl)-1-(3-methyl-4-methoxyphenyl)prop-2-en-1-one

抄録

The title compound (I), a chalcone analog, was synthesized and crystallized in space group P2₁/n with the following cell parameters: a = 14.515(2)Å, b = 7.870(1)Å, c = 15.521(2)Å, β = 111.523(3)°, Z = 4. The molecular backbone is essentially planar and intramoleculary stabilized by C-H…O…H-C hydrogen-bonds of the S (5) type, which is bifurcated at the keto oxygen of the central propanone group. The crystal structure is held together by intermolecular C-H…O hydrogen-bond and π…π stacking interactions.
