Synthesis, crystal structure and Hirshfeld surface analysis of 4-(3-hydroxy-6-methoxy-4-oxo-4 H -chromen-2-yl)benzaldehyde

, 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.
