(E)-3-(4-Chloro-phen-yl)-1-(2,4-dichloro-5-fluoro-phen-yl)prop-2-en-1-one.

ABSTRACT: In the title chalcone derivative, C(15)H(8)Cl(3)FO, the dihedral angle between the two benzene rings is 43.35?(8)°. Weak C-H?O and C-H?Cl intra-molecular inter-actions involving the enone group generate S(5) and S(6) ring motifs, respectively. In the crystal structure, mol-ecules are linked into anti-parallel chains along the a axis. These chains are stacked along the b axis and short Cl?F contacts of 3.100?(1)?Å link adjacent mol-ecules of the anti-parallel chains into dimers.

In the title chalcone derivative, C(15)H(8)Cl(3)FO, the dihedral angle between the two benzene rings is 43.35 (8)°. Weak C-H⋯O and C-H⋯Cl intra-molecular inter-actions involving the enone group generate S(5) and S(6) ring motifs, respectively. In the crystal structure, mol-ecules are linked into anti-parallel chains along the a axis. These chains are stacked along the b axis and short Cl⋯F contacts of 3.100 (1) Å link adjacent mol-ecules of the anti-parallel chains into dimers. ...[more]

(2E)-1-(2,6-Dichloro-3-fluoro-phen-yl)-3-(4-meth-oxy-phen-yl)prop-2-en-1-one.

Project description:There are two independent mol-ecules 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-fluoro-phenyl ring in each mol-ecule, 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 mol-ecules. In the crystal, weak C-H?F and C-H?O inter-actions involving the half-occupied H and F atoms are observed. Weak ?-? stacking inter-actions [centroid-centroid distance = 3.150?(2)?Å] also contribute to the crystal stability.
