(E)-N′-(5-Chloro-2-hy­droxy­benzyl­idene)-2,4-dihy­droxybenzohydrazide methanol monosolvate

In the title compound, C₁₄H₁₁ClN₂O₄·CH₃OH, the mol­ecule adopts an E conformation about the C=N bond. The compound is in the enamine–keto form. The two terminal benzene rings make a dihedral angle of 10.53 (9)°. Intra-mol­ecular O—H...O and O—H...N hydrogen bonding stabilizes the mol­ecular structure. In the crystal, O—H...O hydrogen bonds link the mol­ecules, forming chains running along the b axis.

5,6-Dimethyl-4-phenyl-2H-pyran-2-one

In the title compound, C₁₃H₁₂O₂, the dihedral angle between the pyran­one and phenyl rings is 57.55 (9)°. In the crystal, the mol­ecules are linked by π–π stacking inter­actions between the parallel pyran­one rings of neighboring mol­ecules with distances of 3.5778 (11) Å and 3.3871 (11) Å between the planes. C—H...O interactions also occur.
