(3E,5E)-3,5-Bis(2-chlorobenzylidene)-1-propylpiperidin-4-one

Abstract

The title compound, C22H21Cl2NO, is a derivative of mono-carbonyl analogues of curcumin (MACs). The molecule has an E conformation for each of the olefinic bonds. The 1-propylpiperidin-4-one ring has a distorted chair conformation with the ring N and the C and O atoms of the carbonyl group deviating from the mean plane of the remaining four ring C atoms by 0.682 (2), −0.134 (3) and −0.340 (4) Å, respectively. The dihedral angle between the benzene rings is 26.5 (1)°. In the crystal, molecules are connected by weak C—H...O and C—H...π interactions.
