3,3′-[(4-Nitrophenyl)methylene]bis(4-hydroxy-2H-chromen-2-one)
The molecular conformation of the title compound, C(25)H(15)NO(8), is stabilized by strong intramolecular O—H⋯O hydrogen bonds, resulting in the formation of S (1) (1)(7) ring motifs. In the crystal, π–π stacking interactions are observed between adjacent nitrobenzene and pyranone rings with a cent...

| Sumario: | The molecular conformation of the title compound, C(25)H(15)NO(8), is stabilized by strong intramolecular O—H⋯O hydrogen bonds, resulting in the formation of S (1) (1)(7) ring motifs. In the crystal, π–π stacking interactions are observed between adjacent nitrobenzene and pyranone rings with a centroid–centroid distance of 3.513 (12) Å. The dihedral angles between the nitrobenzene ring and the coumarin ring systems are 65.61 (8) and 66.11 (8)° while the coumarin ring systems are inclined at 65.69 (8)°. |
