Crystal structure and Hirshfeld surface analysis of (2E)-3-(3-bromo-4-fluoro­phen­yl)-1-(3,4-di­meth­oxy­phen­yl)prop-2-en-1-one

In the mol­ecule of the title compound, C(17)H(14)BrFO(3), the aromatic rings are tilted with respect to the enone bridge by 13.63 (14) and 4.27 (15)°, and form a dihedral angle 17.91 (17)°. In the crystal, centrosymmetrically related mol­ecules are linked by pairs of C—H⋯O hydrogen bonds into dimeric units, forming rings of R (2) (2)(14) graph-set motif. The dimers are further connected by weak C—H⋯O hydrogen inter­actions, forming layers parallel to (10[Image: see text]). Hirshfeld surface analysis shows that van der Waals inter­actions constitute the major contribution to the inter­molecular inter­actions, with H⋯H contacts accounting for 29.7% of the surface.
