چکیده
In the title mol-ecule, C(22)H(15)Cl(2)NO, the dihedral angles between the central aromatic ring and the N- and C=O-bonded rings are 43.13 (13) and 0.80 (14)°, respectively. The dihedral angle between the terminal rings is 43.15 (14)°. The major twist occurs about the C(ar)-N bond [C(ar)-C(ar)-N=C = 42.3 (4)°; ar is aromatic].

The title compound, C(17)H(16)ClNO, was synthesized using a solvent-free method by reaction of 4-(dimethyl-amino)benzaldehyde with 4-chloro-acetophenone and NaOH. The chloro-phenyl ring makes a dihedral angle of 18.1 (3)° with the central propenone unit, while the (dimethyl-amino)phenyl group is disordered over two orientations of equal occupancies, which make dihedral angles with the central p...

The asymmetric unit of the title chalcone derivative, C(19)H(20)ClNO, contains two independent mol-ecules, which differ in the conformations of the ethyl groups in the diethyl-amino substituents. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into ribbons propogating in [010]. The crystal packing also exhibits weak C-H⋯π inter-actions.
