(2E)-1-(2,6-Dichloro-3-fluorophenyl)-3-(4-methoxyphenyl)prop-2-en-1-one
There are two independent molecules in the asymmetric unit of the title compound, C(16)H(11)Cl(2)FO(2). The F atom equally populates both meta positions of the 6-dichloro-3-fluorophenyl ring in each molecule, resulting in 0.5 occupancy for both the F and H atoms in these positions. The dihedral a...

Sumario: | There are two independent molecules in the asymmetric unit of the title compound, C(16)H(11)Cl(2)FO(2). The F atom equally populates both meta positions of the 6-dichloro-3-fluorophenyl ring in each molecule, resulting in 0.5 occupancy for both the F and H atoms in these positions. The dihedral angle between the mean planes of the benzene rings are 77.5 (2) and 89.8 (8)°in the two molecules. In the crystal, weak C—H⋯F and C—H⋯O interactions involving the half-occupied H and F atoms are observed. Weak π–π stacking interactions [centroid—centroid distance = 3.150 (2) Å] also contribute to the crystal stability. |
