چکیده
The title hydrazone compound, C(15)H(13)N(3)O(3)·CH(3)OH, crystallized as a methanol solvate. The hydrazone mol-ecule has an E configuration about the C=N bond and is almost planar, with a dihedral angle between the benzene rings of 5.3 (3)°. In the crystal, the hydrazone mol-ecules are linked via the methanol solvent mol-ecule through N-H⋯O and O-H⋯O hydrogen bonds, so forming chains propagating along the a-axis direction.
