چکیده
The title compound, C(20)H(26)N(4)O(2)·CH(3)OH, was prepared by the reaction of 4-diethyl-amino-2-hy-droxy-benzaldehyde with 4-(dimethyl-amino)-benzohydrazide. The dihedral angle between the two benzene rings is 13.6 (3)° and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring. In the crystal, the hydrazone and methanol mol-ecules are linked through inter-molecular O-H⋯O and N-H⋯O hydrogen bonds, forming chains along a.
