(E)-3-Hydroxy-N′-(2-hydroxybenzylidene)-2-naphthohydrazide
The title compound, C(18)H(14)N(2)O(3), is an aroylhydrazone with an approximately planar structure [dihedral angle of 15.27 (13)° between the benzene ring and the naphthyl ring system], stabilized by intra-molecular N-H⋯O and O-H⋯N hydrogen bonds. Inter-molecular O-H⋯O hydrogen bonds with the keto group as acceptor lead to strands along [100]. In terms of graph-set analysis, the descriptor on ...

The title Schiff base, C(14)H(14)N(2)O(2), is close to being planar (r.m.s. deviation for the non-hydrogen atoms = 0.052 Å) and an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, the moleucles are linked by O-H⋯O hydrogen bonds, giving rise to helical chains propagating along the c axis of the tetra-gonal unit cell.
