Sumario: | The title compound, C(23)H(18)N(2)O(2)·0.5H(2)O, a derivative of the biologically active compound curcumin, crystallizes with two organic molecules and a solvent water molecule in the asymmetric unit. Each of the two independent molecules is close to being planar (the dihedral angles between the indole ring systems are approximately 9 and 12°) and each exists in the keto–enol form. There is an intramolecular O—H⋯O hydrogen bond between the keto and enol groups. In the crystal, the components interact by way of N—H⋯N, N—H⋯O and O—H⋯O hydrogen bonds. |
