(Received 22 November 2009; accepted 24 November 2009; online 28 November 2009)

The title Schiff base, C14H14N2O2, is close to being planar (r.m.s. deviation for the non-hydrogen atoms = 0.052 Å) and an intra­molecular 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 tetra­gonal unit cell.

For the crystal structure of 2'-(2-isopropylidene)-2-hydroxybenzohydrazide monohydrate, see: Kraudelt et al. (1996).

Experimental top

The title Schiff base was obtained as a side product from the reaction between 3-hydroxy-2-naphthoic hydrazide (1 g, 5 mmol) and 4-chlorobenzaldehyde (0.7 g, 5 mmol) in acetone. Colourless irregular chunks of (I) were obtained when the solvent was allowed to evaporate slowly.

Refinement top

Anomalous dispersion was negligible and Friedel pairs were merged before refinement.

Carbon-bound H-atoms were placed in calculated positions (C–H 0.95–0.98 Å) and were included in the refinement in the riding model approximation, with U(H) set to 1.2–1.5U(C). The amino and hydroxy H-atoms were located in a difference Fourier map and were refined with distance restraints of N–H 0.88±0.01 Å and O–H 0.84±0.01 Å.
