(1E,4E)-1,5-Bis(4-methyl-phen-yl)penta-1,4-dien-3-one.

ABSTRACT: The title compound, C(19)H(18)O, crystallizes in a non-centrosymmetric space group although the mol-ecule has no chiral centre. The dihedral angle between the aromatic rings is 20.43?(13)°. The structure is stabilized by two intra-molecular hydrogen bonds, and by four ?-? and three C-H?? inter-actions between the aromatic rings. The perpendicular distances between the centroids of the rings involved in the ?-? inter-actions have values of 1.996, 2.061, 2.181 and 2.189?Å.

The title compound, C(19)H(18)O, crystallizes in a non-centrosymmetric space group although the mol-ecule has no chiral centre. The dihedral angle between the aromatic rings is 20.43 (13)°. The structure is stabilized by two intra-molecular hydrogen bonds, and by four π-π and three C-H⋯π inter-actions between the aromatic rings. The perpendicular distances between the centroids of the rings involved in the π-π inter-actions have values of 1.996, 2.061, 2.181 and 2.189 Å. ...[more]
