(E)-3-(4-Fluorophenyl)-1-phenyl-2-propen-1-one
In the title compound, C(15)H(11)FO, the configuration of the keto group with respect to the olefinic double bond is s-cis. The dihedral angle between the planes of the two benzene rings is 10.61 (10)°. The crystal packing is stabilized by C-H⋯π inter-actions involving both benzene rings.

The title compound, C13H9ClO2, exhibits a non-planar geometry; the furan ring being inclined to the benzene ring by 50.52 (16)°. In the crystal, mol-ecules stack along the a axis; however, there are no significant inter-molecular inter-actions present.
متن کاملEthyl (E)-3-(2-hydroxyphenyl)-2-(morpholinocarbonyl)propenoate.
The title compound, C16H19NO5, crystallizes as a centrosymmetric dimer through strong O-H...O hydrogen-bonding interactions between the hydroxyphenyl and morpholinocarbonyl groups. The morpholinocarbonyl group is almost perpendicular to the propenoate moiety. Electron delocalization in the N-C(=O) fragment leads to the formation of hydrogen-bonded S(5) ring motifs through C-H...O interactions.
متن کاملCrystal structure of the chalcone (E)-3-(furan-2-yl)-1-phenylprop-2-en-1-one
The title chalcone derivative, C13H10O2, adopts an E conformation about the C=C double bond. The mol-ecule is composed of a furanyl and a phenyl ring, bridged by an α,β-unsaturated carbonyl system, which are inclined to one another by 24.07 (7)°. In the crystal, mol-ecules are connected by weak C-H⋯O hydrogen bonds involving the carbonyl O atom acting as a trifurcated acceptor and C-H⋯π inter-a...
متن کاملCrystal structure of 3-amino-5,5-dimethyl-2-[(E)-2-nitroethenyl]cyclohex-2-en-1-one
The asymmetric unit of the title compound, C10H14N2O3, contains two independent mol-ecules with similar conformations. In the both mol-ecules, the cyclo-hexene rings adopt the same envelope conformation with the flap C atoms lying 0.658 (3) and 0.668 (3) Å from the mean planes formed by the remaining atoms. In the crystal, adjacent mol-ecules are connected via N-H⋯O hydrogen bonds and weak C-H⋯...
