N'-[4-(Dimethyl-amino)benzyl-idene]-3-hydr-oxy-2-naphthohydrazide.

ABSTRACT: 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.
