The title compound, C21H24O6, is the reduced form of curcumin, and exhibits important cosmoceutical properties. The molecule is non-planar and the benzene rings positioned at the ends of the heptane chain are orthogonally placed, with a dihedral angle of 84.09 (7)degrees between them. The molecular geometry and H-atom locations reveal that the `heptane-3,5-dione' moiety exists in the keto-enol form, with the hydroxy H atom disordered over two adjacent sites. The packing of the molecules in the lattice is directed by strong O-H...O intermolecular hydrogen bonds, which generate two-dimensional sheets. These sheets are linked by C-H...O hydrogen bonds and weak C-H... interactions to develop a three-dimensional network.
