چکیده
The asymmetric unit of the title compound, C(17)H(19)N(3)O(3)·CH(4)O, comprises two Schiff base mol-ecules and two methanol solvent mol-ecules. The Schiff base mol-ecules are approximately planar, with r.m.s. deviations from the planes defined by the non-H atoms of 0.107 and 0.154 Å, and with dihedral angles between the benzene rings of 4.49 (15) and 8.39 (15)°, respectively. This near-planarity is assisted by the formation of intra-molecular O-H⋯N hydrogen bonds in each mol-ecule. In the crystal, the components are linked by N-H⋯O and O-H⋯O hydrogen bonds to form chains along [010].
