Weak hydrogen bonds in 5-(4-methoxy­phen­yl)-1-phenyl­pent-4-ene-1,3-dione

The title mol­ecule, C₁₈H₁₆O₃, exists in the enolized form and displays a strong intra­molecular hydrogen bond. Except for van der Waals inter­actions, the inter­molecular contacts are dominated by weak hydrogen bonding of the type C—H...O and aromatic C—H...π.
