The title compound, C17H14N3O2+·NO3−, is an aroylhydrazone-based material consisting of a 4-(hydrazinecarbonyl)pyridinium cation and a nitrate anion. In the cation, the dihedral angle between the benzene ring and the naphthalene ring system is 2.20 (7)°. In the cation, the configuration about the C=N bond is E. There is an intramolecular O—H⋯N hydrogen bond in the cation, and the supramolecular structure is stabilized by intermolecular N—H⋯O hydrogen bonds and weak C—H⋯O contacts between the cation and the nitrate anion.

All reagents were commercially available and used as received. A methanol (10 ml) solution of 2-hydroxy-1-naphthaldehyde (1.63 mmol) was dropwise added to a methanol solution (10 ml) of 4-pyridine carboxylic acid hydrazide (1.63 mmol), and the mixture was refluxed for 3 hrs. Then the solution was evaporated on a steam bath to 5 ml and cooled to room temperature. The resultant yellow precipitate was separated and filtered off, washed with 5 ml of cooled methanol and then dried in air. 1 mmol of this solid was placed in one arm of a branched tube with 2 mmol of Mn(NO3)2.4H2O. Methanol was carefully added to fill the arms, the tube was sealed and the arm containing the reagents was immersed in an oil bath at 60 °C while the other arm was kept at ambient temperature. After 4 days, crystals were deposited in the cooler arm, which were filtered off and air dried. Yield: 85%, Selected IR spectrum: 3430 (s, broad), 1630 (s), 1600 (m), 1549 (m), 1384 (versus), 1291 (m), 972 (m), 834 (s), 764 cm-1 (m).
The hydrogen atoms of the N—H and O—H groups were positioned geometrically and refined as riding atoms with, N—H = 0.88 Å and Uiso(H) = 1.2 Ueq(N), O—H = 0.84 Å and Uiso(H) = 1.5 Ueq(O). The C—H hydrogen atoms were positioned geometrically and refined as riding atoms with C—H = 0.95 Å and Uiso(H) = 1.2 Ueq(C).

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, a class of Schiff base, derived from the condensation of acid hydrazides (R–CO–NH–NH2) with aromatic 2-hydroxy carbonyl compounds are important tridentate O, N, O-donor ligands. As biologically active compounds, hydrazones find application in the treatment of diseases such as anti-tumor, tuberculosis, leprosy and mental disorder. Hydrazone ligands create environment similar to biological systems by usually making coordination through oxygen and nitrogen atoms. Furthermore hydrazones have wide spread applications in fields such as coordination chemistry, bioinorganic chemistry, in magnetic, electronic, nonlinear optically active and fluorescent compounds. Aroylhydrazone complexes seem to be a good candidate for catalytic oxidation studies because of their resist to oxidation (Hosseini Monfared et al., 2010b).
As part of our studies on the synthesis and characterization of hydrazone derivatives, we report here the crystal structure of (E)-4-(2-((2-hydroxynaphthalen-1-yl)methylene)hydrazinecarbonyl)pyridinium nitrate. The asymmetric unit of C17H14N4O5, consists of a (E)-4-(2-((2-hydroxynaphthalen-1-yl)methylene)hydrazinecarbonyl)pyridinium cation and a nitrate anion (Fig. 1). The dihedral angle between the mean planes of the benzene and naphthalene rings is 2.20 (7)°. The cation displays a trans configuration with respect to the C=N and N—N bonds. It is to note that the overall structure of the cation is very similar to that found for free ligand Richardson & Bernhardt (1999). The packing diagram of the title compound is shown in Fig. 2. There is a strong intramolecular O—H···N hydrogen bond in which the N of the azomethine group (–C=N–) acts as hydrogen acceptor for the hydrogen O—H group attached to the naphthalene ring. Two intermolecular N—H···O hydrogen bonds are formed between cation and anion where NO3- acts as hydrogen bonds acceptor (Fig. 3). The supramolecular structure is further stabilised by C—H···O interactions.
