All reagents were commercially available and used as received. A methanol (10 ml) solution of 2-hydroxy-1-naphtaldehyde (1.5 mmol) was drop-wise added to a methanol solution (10 ml) of 2-furanecarboxylic acid hydrazide (1.5 mmol), and the mixture was refluxed for 3 h. Then the solution was evaporated on a steam bath to 5 cm3 and cooled to room temperature. Yellow precipitates of the title compound were separated and filtered off, washed with 3 ml of cooled methanol and then dried in air. X-ray quality crystals of the title compound were obtained from methanol by slow solvent evaporation. Yield: 82%, mp 197-198 °C.
The hydroxyl hydrogen atoms were located by Fourier analysis and refined using the riding model with d(O—H) = 0.82Å [Uiso(H) = 1.5Ueq(O)]. C-bonded H atoms were positioned geometrically (C—H = 0.93 Å) and treated as riding on their parent atoms [Uiso(H) = 1.2Ueq(C)].
Hydrazone ligands derived from the condensation of aliphatic acid
or aromatic acid with aromatic 2-hydroxy are important tridentate O, N,O-donor ligands. These compounds, due to their facile keto-enol and the availability of several potential donor sites, can coordinate to metals. Furthermore, the possibility of makes their study interesting (Ghosh et al., 2007). have wide spread applications in coordination, analytical and bioinorganic chemistry, and display magnetic, electronic, NLO and fluorescent properties in biologically active compounds (Prathapachandra Kurup et al., 2007). They find applications in the treatment of diseases such as anti-tumor, tuberculosis, leprosy and mental disorder (Nagaraju et al., 2009). As part of our studies on the synthesis and characterization of aroylhydrazone derivatives, we report here the of C16H12N2O3.In the title compound, C16H12N2O3, the dihedral angle between the mean planes of the naphthalene and furan rings is 21.3 (6)° (Fig.1). The angle formed between the menn planes of the naphthalene substituted hydroxy group (C11/C10/C1/O1/H1) and the 2-carbohydrazonic acid furan substituted hydroxy group (N1/N2/C12/O2/H22) is 17.9 (1)°. Bond distances and angles are in normal ranges (Allen et al., 1987). Crystal packing is stabilized by O1—H1···N1 intramolecular hydrogen bonds which form an S11(6) graph-set motif (Bernstein et al., 1995), Etter et al., 1990), (Fig. 2).

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. |

Hydrazone ligands derived from the condensation of aliphatic acid hydrazides or aromatic acid hydrazides with aromatic 2-hydroxy carbonyl compounds are important tridentate O, N,O-donor ligands. These compounds, due to their facile keto-enol tautomerization and the availability of several potential donor sites, can coordinate to metals. Furthermore, the possibility of tautomerism makes their study interesting (Ghosh et al., 2007). Hydrazones have wide spread applications in coordination, analytical and bioinorganic chemistry, and display magnetic, electronic, NLO and fluorescent properties in biologically active compounds (Prathapachandra Kurup et al., 2007). They find applications in the treatment of diseases such as anti-tumor, tuberculosis, leprosy and mental disorder (Nagaraju et al., 2009). As part of our studies on the synthesis and characterization of aroylhydrazone derivatives, we report here the crystal structure of C16H12N2O3.
In the title compound, C16H12N2O3, the dihedral angle between the mean planes of the naphthalene and furan rings is 21.3 (6)° (Fig.1). The angle formed between the menn planes of the naphthalene substituted hydroxy group (C11/C10/C1/O1/H1) and the 2-carbohydrazonic acid furan substituted hydroxy group (N1/N2/C12/O2/H22) is 17.9 (1)°. Bond distances and angles are in normal ranges (Allen et al., 1987). Crystal packing is stabilized by O1—H1···N1 intramolecular hydrogen bonds which form an S11(6) graph-set motif (Bernstein et al., 1995), Etter et al., 1990), (Fig. 2).
