(E)-3-(3,4-Dimethoxy-phen-yl)-1-(2-thien-yl)prop-2-en-1-one.

ABSTRACT: The title compound, C(15)H(14)O(3)S, has two symmetry-independent mol-ecules in the asymmetric unit with almost identical geometry. The dihedral angle between the benzene and thio-phene rings is 1.61?(11)° in one mol-ecule and 7.21?(11)° in the other. In both mol-ecules, C-H?O hydrogen bonds generate rings of graph-set motif S(5). The crystal structure is stabilized by C-H?O hydrogen bonds, C-H?? inter-actions and ?-? inter-actions involving the benzene and thio-phene rings, with centroid-centroid distances of 3.5249?(13) and 3.6057?(13)?Å.

The title compound, C(15)H(14)O(3)S, has two symmetry-independent mol-ecules in the asymmetric unit with almost identical geometry. The dihedral angle between the benzene and thio-phene rings is 1.61 (11)° in one mol-ecule and 7.21 (11)° in the other. In both mol-ecules, C-H⋯O hydrogen bonds generate rings of graph-set motif S(5).

Project description:In the title mol-ecule, C(15)H(14)O(4), the benzene and furyl rings are inclined to each other with a dihedral angle of 41.5 (1)°. An intra-molecular C-H⋯O hydrogen-bond inter-action generates an S(5) ring motif. In the crystal structure, mol-ecules are stacked along the b axis and the crystal packing is stabilized by inter-molecular C-H⋯O and C-H⋯π inter-actions. In addition, π-π stacking inter-actions with a centroid-to-centroid distance of 3.5855 (11) Å are observed.

(E)-1-(2,5-Dichloro-3-thien-yl)-3-(3,4-dimeth-oxy-phen-yl)prop-2-en-1-one.

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.

(E)-3-(2,4-Dichloro-phen-yl)-1-(2-thien-yl)prop-2-en-1-one.

Project description:In the title chalcone derivative, C(13)H(8)Cl(2)OS, the prop-2-en-1-one unit and the thio-phene and 2,4-dichloro-phenyl rings are each essentially planar. The inter-planar angle between the thio-phene and 2,4-dichloro-phenyl rings is 19.87 (6)°. Weak intra-molecular C-H⋯O and C-H⋯Cl inter-actions involving the prop-2-en-1-one unit generate an S(5)S(5) ring motif. In the crystal structure, mol-ecules are linked into head-to-tail zigzag chains along the a axis and adjacent chains are cross-linked. These cross-linked chains are arranged into sheets parallel to the ab plane. The crystal structure is stabilized by weak C-H⋯O, C-H⋯Cl and C-H⋯π inter-actions. A π-π inter-action was also observed with a centroid-centroid distance of 3.6845 (6) Å.

(E)-1-(2-Thien-yl)-3-(2,4,5-trimethoxy-phen-yl)prop-2-en-1-one.

Project description:In the title mol-ecule, C(16)H(16)O(4)S, the enone fragment, thio-phene ring and benzene ring are individually essentially planar. The thio-phene ring is disordered over two sites, corresponding to a rotation of approximately 180° about the single C-C bond to which it is attached. The approximate ratio of occupancies for the major and minor components is 0.872 (2):0.128 (2). The major component of the thio-phene ring and the benzene ring are twisted from each other by 13.92 (19)°. An intra-molecular C-H⋯O hydrogen bond generates an S(5)S(5) ring motif. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen-bonding inter-actions. In addition, a π-π stacking inter-action, with a centroid-centroid distance of 3.852 (2) Å, and short S⋯O [2.9378 (12) Å] and O⋯O [2.5811 (16) Å] contacts are observed.

(E)-3-(4-Chloro-phen-yl)-1-(2-thien-yl)prop-2-en-1-one.

Project description:The title compound, C(13)H(9)ClOS, adopts an E configuration with respect to the C=C double bond of the propenone unit. The thienyl and benzene rings are slightly twisted from each other, making a dihedral angle of 6.38 (3)°. An intra-molecular C-H⋯O hydrogen bond generates an S(5) ring motif. A weak inter-molecular C-H⋯O inter-action, a short intra-molecular S⋯O contact [2.932 (2) Å] and two π-π inter-actions between the thienyl and benzene rings are observed.

3-(2-Chloro-6-fluoro-phen-yl)-1-(2-thien-yl)prop-2-en-1-one.

Project description:The title chalcone derivative, C(13)H(8)ClFOS, crystallized as an inversion twin with two independent mol-ecules in the asymmetric unit. The thio-phene rings in both mol-ecules are disordered over two sites: the ratios of occupancies for the major and minor components in the two mol-ecules are 0.820 (2):0.180 (2) and 0.853 (2):0.147 (2). The dihedral angles between the major and minor components of the thio-phene and benzene rings are 1.13 (18) and 2.2 (6)°, respectively, in one mol-ecule, with corresponding values 6.09 (17) and 1.3 (6)° in the other. Weak intra-molecular C-H⋯O and C-H⋯F inter-actions involving the prop-2-en-1-one group generate an S(5)S(5) ring motif, whereas a weak intra-molecular C-H⋯Cl contact generates an S(6) ring motif. In the crystal structure, mol-ecules of both the major and minor components are linked into infinite one-dimensional chains along the b axis. The crystal structure is stabilized by weak C-H⋯O, C-H⋯F, C-H⋯Cl and C-H⋯π inter-actions.

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

Project description:In the title compound, C17H14F2O3, the dihedral angle between the benzene rings is 20.56 (8)° and the H atoms at the central propenone group are trans configured. One of the F atoms is disordered over two positions (occupancy ratio 0.57:0.43) and was refined using a split model. In the crystal, the molecules are linked into centrosymmetrical dimers and are further connected into a three-dimensional network via weak C-H⋯O interactions.

Project description:The mol-ecule of the title compound, C(15)H(9)BrCl(2)O, is shown to be the E isomer, with the 3,4-dichloro-benzoyl and p-bromo-phenyl substituents in trans positions with respect to the chalcone olefin bond.
