ABSTRACT
In the title curcumin-ionone derivative, C(20)H(23)NO(3), the dihedral angle between the cyclo-hexene and benzene rings is 21.03â
(8)°, with both double bonds in the inter-linking olefinic chain adopting E conformations. Two of the methyl-ene groups of the ß-ionone ring are disordered over two sets of sites with occupancy ratios of 0.500.50 and 0.600.40. In the crystal, mol-ecules are linked by weak C-Hâ¯O hydrogen bonds into zigzag chains extending along the b axis.
