N′-[4-(Dimethylamino)benzylidene]-3-hydroxy-2-naphthohydrazide
نویسنده
چکیده
The title compound, C(20)H(19)N(3)O(2), was obtained by the condensation of 4-(dimethyl-amino)benzaldehyde with 3-hydr-oxy-2-naphthohydrazide. The mol-ecule is approximately planar, with an intra-molecular N-H⋯O hydrogen bond involving the imino H atom and the hydr-oxy O atom. The dihedral angle between the benzene ring and the naphthyl mean plane is 2.72 (13)°. In the crystal structure, symmetry-related mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds, forming chains propagating in the c-axis direction.
