In the title molecule, C16H16N2O3, intramolecular O—H⋯O hydrogen bonds influence the molecular conformation. Intermolecular O—H⋯O hydrogen bonds [O⋯O = 2.922 (2) Å] link the molecules into centrosymmetric dimers. Weak intermolecular C—H⋯O interactions assemble these dimers into layers parallel to the bc plane.

A highly puckered 60-membered metalladiazamacrocycle was reported by Moon et al. (2006), and two manganese metallacrowns with the ligand N-acyl-3-hydroxy-2-naphthalenecarbohydrazide were reported by Dou et al. (2006). The ligand 1-benzoyl-3,5-dimethyl-5-(1-benzoylhydrazido)pyrazoline was first synthesized by Mukhopadhyay & Pal (2004).

0.21 ml of acetylacetone (0.205 g, 2.05 mmol) were added into a methanol solution (15 ml) of 3-hydroxy-2-naphthoylhydrazine (0.404 g, 2 mmol). The mixture was refluxed for 3 h followed by evaporation to approximate 1/3 of the original volume on a rotary evaporator, then the solution was cooled to room temperature. After the solution was allowed to stand for 2 weeks, yellow block crystals suitable for X-ray
was obtained. Yield: 0.400 g, 70.37%. m.p.: 565–567 K. Anal. for C16H16N2O3: Calc. C, 67.53; H, 5.63; N, 9.85; Found: C, 67.20; H, 5.49; N, 9.28%. The No. of CCDC: 693975.All H atoms were placed in geometrically idealized positions (C—H 0.93–0.96 Å, O—H 0.82 Å) and treated as riding on their parent atoms, with Uiso(H)= 1.2–1.5Ueq of the parent atom.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Aroylhydrazine ligands have gained an increasing attraction due to their interesting chemical activities (Moon et al., 2006). As an extension of our work on the structural characterization of aroylhydrazine derivatives, along with our work of successful assembly of two azametallacrowns using N-acyl-3-hydroxy-2-naphthalenecarbohydrazide (Dou et al., 2006), the title compound, (I), was synthesized and characterized.
Pyrazoline ring in (I) is nearly co-planar with the mean deviation of 0.0379 Å from its least-squares plane, and the distances of N1—N2, C13—N1 and C15—N2 are 1.403 (2), 1.498 (2) and 1.275 (2) Å, respectively, which are in agreement with those of the analogous compound (Mukhopadhyay & Pal, 2004). The dihedral angle between the pyrazoline ring and naphthalene ring is 28.2 (3)°.
There are intramolecular O2—H2···O1 and O3—H3···O1 hydrogen bonds (Table 1, Fig. 1), which influence the molecular conformation. The intermolecular O—H···O (Table 1) hydrogen bonds link molecules into centrosymmetric dimers, and the weak intermolecular C—H···O interactions (Table 1) assemble further these dimers into the layers parallel to bc-plane.
