Bottom Line: In the title curcumin-ionone derivative, C(20)H(23)NO(3), the dihedral angle between the cyclo-hexene and benzene rings is 21.03 (8)°, with both double bonds in the inter-linking olefinic chain adopting E conformations.Two of the methyl-ene groups of the β-ionone ring are disordered over two sets of sites with occupancy ratios of 0.50:0.50 and 0.60:0.40.In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds into zigzag chains extending along the b axis.
