Project description:In the title compound, C(15)H(12)Cl(2)O(3)S, the prop-2-en-1-one (enone) fragment is almost planar [C-C-C-O = 2.2?(4)°] and it subtends dihedral angles of 11.9?(2) and 11.0?(2)° with the thio-phene and benzene rings, respectively. The dihedral angle between the aromatic rings is 3.47?(16)°. In the crystal, weak C-H?O and C-H?Cl inter-actions link the mol-ecules, leading to R(2) (2)(14), R(2) (2)(24) and C(11) supra-molecular motifs occurring within the three-dimensional network. Weak aromatic ?-? stacking [centroid-centroid separations = 3.6823?(15) and 3.8722?(15)?Å] may also help to consolidate the packing.

(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.

Project description:The asymmetric unit of the title compound, C(17)H(19)NOS, contains two independent mol-ecules which differ in the dihedral angles between the five- and six-membered rings [12.52?(10) and 4.63?(11)°].
