Abstract:
The asymmetric unit of the title compound, C17H12O5, contains one crystallographically independent mol-ecule featuring a chromenone fragment with hy-droxy and meth-oxy substituents and a benzaldehyde group. Intra-molecular O-H⋯O, C-H⋯O hydrogen bonds are observed. In the crystal, mol-ecules are linked by O-H⋯O inter-molecular bonds, forming chains along [201]. The Hirshfeld surface analysis shows that the H⋯H and O⋯H/H⋯O contacts dominate the crystal packing with contributions of 34.2% and 27.6%, respectively.

As the self-condensation of ketones is generally not favored in basic conditions, the self-condensed products do not form in the reaction between ketones and benzaldehyde. The general reaction of Claisen–Schmidt condensation is...
