Two independent mol-ecules comprise the asymmetric unit of the title chalcone, C(25)H(17)Cl(2)NO, and while each has an E configuration about the ethyl-ene double bond, they differ in the relative orientations of the carbonyl and ethyl-ene double bonds within the prop-2-en-1-one residues, i.e. anti and syn. For each mol-ecule, the benzene [dihedral angles = 71.04 (9) and 73.34 (12)°] and prop-2-en-1-one [C-C-C-O = 91.2 (2) and -119.1 (3)°] substituents are twisted out of the plane of the quinoli ...[more]
