(1E,4E)-1,5-Bis(4-methyl­phen­yl)penta-1,4-dien-3-one

The title compound, C(19)H(18)O, crystallizes in a non-centrosymmetric space group although the mol­ecule has no chiral centre. The dihedral angle between the aromatic rings is 20.43 (13)°. The structure is stabilized by two intra­molecular hydrogen bonds, and by four π–π and three C—H⋯π inter­actio...

description The title compound, C(19)H(18)O, crystallizes in a non-centrosymmetric space group although the mol­ecule has no chiral centre. The dihedral angle between the aromatic rings is 20.43 (13)°. The structure is stabilized by two intra­molecular hydrogen bonds, and by four π–π and three C—H⋯π inter­actions between the aromatic rings. The perpendicular distances between the centroids of the rings involved in the π–π inter­actions have values of 1.996, 2.061, 2.181 and 2.189 Å.
