In the title curcumin–ionone derivative, C(20)H(23)NO(3), the dihedral angle between the cyclo­hexene and benzene rings is 21.03 (8)°, with both double bonds in the inter­linking olefinic chain adopting E conformations. Two of the methyl­ene groups of the β-ionone ring are disordered over two sets o...

description In the title curcumin–ionone derivative, C(20)H(23)NO(3), the dihedral angle between the cyclo­hexene and benzene rings is 21.03 (8)°, with both double bonds in the inter­linking olefinic chain adopting E conformations. Two of the methyl­ene 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, mol­ecules are linked by weak C—H⋯O hydrogen bonds into zigzag chains extending along the b axis.
