In the title hydrate, C19H16N2O4·H2O, the 4H-chromen-4-one segment is slightly twisted, with a dihedral angle between the two six-membered rings of 3.30 (5)°. The dihedral angles between the plane of the pyranone ring and the hydrazide plane and between the planes of the pyranone ring and the benzene ring of the p-methoxybenzene unit are 26.69 (4) and 2.23 (3)°, respectively. The molecule is connected to the solvent water molecule by an N—H⋯O hydrogen bond. In the crystal, there are π–π stacking interactions between centrosymmetrically related pyranone rings [centroid–centroid distance = 3.5394 (9) Å], as well as bridges formed by the water molecules via O—H⋯O hydrogen bonds.

4-Methoxybenzoylhydrazide (1.00 mmol), 6-methyl-3-formylchromone (1.00 mmol), and a few drops of acetic acid were dissolved in 25 mL of benzene and the mixture was refluxed with a Dean-Stark apparatus for 6 h. After cooling, the precipitates were collected, washed with n-hexane, and dried (yield 68.9%). 1H NMR (400 MHz, DMSO-d6): δ = 2.45 (s, 3H), 3.84 (s, 3H), 7.06 (d, 1H, J = 8.8 Hz), 7.63 (d, 1H, J = 8.3 Hz), 7.69 (dd, 1H, J = 2.5 and 8.3 Hz), 7.93 (d, 1H, J = 8.8 Hz), 7.94 (d, 1H, J = 2.5 Hz), 8.63 (s, 1H), 8.79 (s, 1H), 11.82 (s, 1H). DART-MS calcd for [C19H16N2O4 + H+]: 337.119, found 337.194. Single crystals suitable for X-ray diffraction were obtained by slow evaporation of an N,N-dimethylformamide solution of the title compound at room temperature.
The C(sp2)- and N(sp2)-bound hydrogen atoms were placed in geometrical positions [C–H 0.95 Å, Uiso(H) = 1.2Ueq(C), N–H 0.88 Å, Uiso(H) = 1.2Ueq(N)], and refined using a riding model. Hydrogen atoms of methyl groups were found in a difference Fourier map, and a rotating group model was applied with distance constraint [C–H = 0.98 Å, Uiso(H) = 1.2Ueq(C)]. Hydrogen atoms of the water molecule were found in a difference Fourier map, and were refined using a riding model.
Schiff base derivatives of 3-formyl chromones have attracted much attention due to their biological functions such as enzyme inhibition (Khan et al. 2009; Tu et al. 2013). We herein report the
of the title compound, which was obtained from the condensation reaction of 6-methyl-3-formylchromone with 4-methoxybenzoylhydrazide in benzene.The 4H-chromen-4-one segment segment is slightly twisted with a dihedral angle between the two 6-membered rings of 3.30 (5)°. The dihedral angles between the pyranone ring and the hydrazide plane (C11/N1/N2/C12) and between the pyranone ring and the benzene ring of the p-methoxybenzene unit are 26.69 (4) and 2.23 (3)°, respectively. The molecule is connected to the solvent water molecule byan N–H···O hydrogen bond.
In the crystal, there are π-π stacking interactions between centrosymmetrically-related pyranone rings [centroid–centroidi distance = 3.5394 (9) Å, i: –x + 1, –y + 1, –z + 1] as well as bridges formed by the water molecules via O–H···O hydrogen bonds (Fig. 2).

Schiff base derivatives of 3-formyl chromones have attracted much attention due to their biological functions such as enzyme inhibition (Khan et al. 2009; Tu et al. 2013). We herein report the crystal structure of the title compound, which was obtained from the condensation reaction of 6-methyl-3-formylchromone with 4-methoxybenzoylhydrazide in benzene.
The 4H-chromen-4-one segment segment is slightly twisted with a dihedral angle between the two 6-membered rings of 3.30 (5)°. The dihedral angles between the pyranone ring and the hydrazide plane (C11/N1/N2/C12) and between the pyranone ring and the benzene ring of the p-methoxybenzene unit are 26.69 (4) and 2.23 (3)°, respectively. The molecule is connected to the solvent water molecule byan N–H···O hydrogen bond.
In the crystal, there are π-π stacking interactions between centrosymmetrically-related pyranone rings [centroid–centroidi distance = 3.5394 (9) Å, i: –x + 1, –y + 1, –z + 1] as well as bridges formed by the water molecules via O–H···O hydrogen bonds (Fig. 2).
