title: (E)-1-(2,4-Dimethyl-quinolin-3-yl)-3-(4-methyl-phen-yl)prop-2-en-1-one.
abstract: In the title compound, C(21)H(19)NO, there are two mol-ecules in the asymmetric unit (Z' = 2). There are π-π inter-actions between these two mol-ecules [centroid-centroid distance = 3.678 (2) Å], as well as a weak C-H⋯O inter-action. The conformation adopted by the two mol-ecules is such that the quinoline mean plane and the benzene ring are almost perpendicular [89.04 (5) and 76.89 (4)°]. In each mol-ecule, the methyl group of the tolyl ring is disordered over two conformations, with occupancy ratios of 0.56 (3):0.44 (3) and 0.65 (3):0.35 (3).
