Deskripsi
The title compound, C16H15Cl2N3O2·CH3OH, a Schiff base molecule, is prepared by the reaction of 3,5-dichlorosalicylaldehyde with 4-dimethylaminobenzohydrazide in methanol. The Schiff base molecule is approximately planar, with a mean deviation from the least-squares plane defined by the non-H atoms of 0.0452 (3) Å, and with a dihedral angle between the benzene rings of 4.2 (3)°. This planarity is assisted by the formation of an intramolecular O—H...N hydrogen bond. In the crystal, adjacent Schiff base molecules are linked by two methanol molecules through N—H...O and O—H...O hydrogen bonds, forming dimers.
