title: (E)-1-(4-Chloro-phen-yl)-3-[4-(diethyl-amino)phen-yl]prop-2-en-1-one.
abstract: 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.
