Isonicotinic acid hydrazide (1.4 g, 10 mmol) was dissolved in 15 ml of absolute ethanol. To this solution 2,3-dihydroxy benzaldehyde (1.38 g, dissolved in 10 ml absolute ethanol) was added. The reaction mixture was refluxed for 5 h and then cooled to room temperature, giving a clear yellow solution. After keeping the solution in air for 10 days, yellow crystals of the title compound, suitable for X-ray
were obtained. The crystals were isolated washed with cold absolute ethanol and dried in air. Yield 79%. Anal. Calcd. for C13H11N3O3: C 60.70, H 4.31, N 16.33%. Found: C 60.64, H 4.39, N 16.39%. Spectroscopic and other synthetic details are given in the archived CIF.Schiff bases are typically formed by the condensation of a primary amine and an aldehyde. Also,
are a that contains a carbon-nitrogen (C=N) double bond (an imine group). These bases play an important role in inorganic chemistry as they easily form stable complexes with most transition metal ions. The development of the field of bioinorganic chemistry has increased the interest in Schiff base complexes, since it has been recognized that many of these complexes may serve as models for biologically important species (Abou-Melha 2008; Chohan et al., 1999). The remarkable biological activity of acid R—CO—NH—NH2, a class of Schiff base, their corresponding aroylhydrazones, R—CO—NH—N=CH—R' and the dependence of their mode of with transition metal ions present in the living system have been of significant interest in the past. Isonicotinic acid hydrazide (INH) is a drug of proven therapeutic importance and is used against a wide spectrum of bacterial ailments, e.g., tuberculosis (Agarwal et al., 2005, Savanini et al., 2002). derived from the condensation of isonicotinic acid hydrazide with pyridine have been found to show better antitubercular activity than INH (Kriza et al., 2010, Agarwal et al.,2006, Durgaprasad et al.,1973).The molecular structure of the two independent molecules (a and b) of the title compound are shown in Fig. 1. The title molecule comprises three functional groups: pyridine, phenyl and hydrazone. Both molecules, a and b, have the E configuration at the central C=N bond (Fig. 1). One of the molecules (b) is twisted while the other (a) is planar, with the dihedral angles between the phenyl and pyridine rings being 28.02 (6)° and 2.42 (9)° in molecules (b) and (a), respectively. Because of this different conformation molecules (a) and (b) have different hydrogen bonding patterns. Molecule (a) is influenced by the O—H···N, O—H···O intramolecular hydrogen bonds and C—H···O intramolecular interactions, and the intermolecular N—H···N, O—H···O, C—H···O and C—H···N hydrogen bonds (Table 1). Molecule (b) is influenced by O—H···N and O—H···O intramolecular hydrogen bonds and N—H···N, O—H···O and two C—H···O intermolecular hydrogen bonds (Table 1).
The N1—N2 (molecule a) and N4—N5 (molecule b) bond distances of 1.3726 (15) Å and 1.3679 (16) Å, respectively, are appreciably shorter than a typical N—N single bond, such as that found in free 2,4-dinitrophenylhydrazone, i.e. 1.405 (6) Å; this suggests the existence of a delocalized double bond system (Zülfikaroğlu et al., 2009). The N1═C7 (molecule a) and N4═ C20 (molecule b) bond distances of 1.2782 (18) Å and 1.276 (2) Å, respectively, are typical for a double bond. For both molecules, the central torsion angles are C7—N1—N2—C8 at 177.63 (14)° (molecule a) and C21—N5—N4—C20 at 174.77 (14)° (molecule b). Also, the torsion angles N4—C20—C14—C15 and C23—C22—C21—N5 in the molecule (b) are 2.16 (22)° and 22.12 (20)°, respectively.
Interestingly, in the crystal the hydrogen bonding (O2—H2O···O4 and O5—H5O···O1) leads to the dimerization of the molecules (Avasthi et al., 2002) (Table 1), as shown in Fig. 2, and finally to the formation of a layer-like structure (Fig. 3).

Experimental. Elemental analyses were performed using standard methods at TUBİTAK (The Turkish Scientific Research Centre). The IR spectrum was recorded on a Vertex 80v sample Compartment RT-DLaTGS spectrophotometer operating within 4000–500 cm-1. 1H NMR spectra were obtained on BRUKER DPX-400, 400 MHz High Performance Digital FT-NMR spectrometer using deuterated as solvent. Spectroscopic characterization of the title compound: The structure was verified by means of IR, 1H NMR (DMSO), UV-VIS spectral data and elemental analyses. In the 1H NMR spectra of I the azomethine proton appears as a singlet at 8.68 p.p.m.. A single resonance for the proton in –NHN= group is observed at 12.51 p.p.m.. Chemical shifts of the protons on the pyridine ring exhibit two sets of signals in 8.93–8.67 p.p.m. as a doublet and in 8.02–7.74 p.p.m. as doublet, too. The phenyl protons of 1 resonate at 7.07–6.70 p.p.m.. The protons of the phenolic OH are observed at 11.14 p.p.m. and 9.59 p.p.m. as singlets. The IR spectrum of the I shows a weak band at 3520 cm-1 assigned to ν OH of the phenolic group. The deformation vibration, δ of the phenolic OH groups appears at 1272 cm-1. The NH stretching absorption appears as strong band 3392 cm-1. Another important band occurs at 1680 cm-1 attributed to ν(C=0) (carbonyl) mode. Azomethine ν(C=N) absorption band appear at 1561 cm-1. The medium intensity band at 1061 cm-1 is ascribed to ν(N—N) vibration. |
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. |

Schiff bases are typically formed by the condensation of a primary amine and an aldehyde. Also, Schiff bases are a functional group that contains a carbon-nitrogen (C=N) double bond (an imine group). These bases play an important role in inorganic chemistry as they easily form stable complexes with most transition metal ions. The development of the field of bioinorganic chemistry has increased the interest in Schiff base complexes, since it has been recognized that many of these complexes may serve as models for biologically important species (Abou-Melha 2008; Chohan et al., 1999). The remarkable biological activity of acid hydrazides R—CO—NH—NH2, a class of Schiff base, their corresponding aroylhydrazones, R—CO—NH—N=CH—R' and the dependence of their mode of chelation with transition metal ions present in the living system have been of significant interest in the past. Isonicotinic acid hydrazide (INH) is a drug of proven therapeutic importance and is used against a wide spectrum of bacterial ailments, e.g., tuberculosis (Agarwal et al., 2005, Savanini et al., 2002). Hydrazones derived from the condensation of isonicotinic acid hydrazide with pyridine aldehydes have been found to show better antitubercular activity than INH (Kriza et al., 2010, Agarwal et al.,2006, Durgaprasad et al.,1973).
The molecular structure of the two independent molecules (a and b) of the title compound are shown in Fig. 1. The title molecule comprises three functional groups: pyridine, phenyl and hydrazone. Both molecules, a and b, have the E configuration at the central C=N bond (Fig. 1). One of the molecules (b) is twisted while the other (a) is planar, with the dihedral angles between the phenyl and pyridine rings being 28.02 (6)° and 2.42 (9)° in molecules (b) and (a), respectively. Because of this different conformation molecules (a) and (b) have different hydrogen bonding patterns. Molecule (a) is influenced by the O—H···N, O—H···O intramolecular hydrogen bonds and C—H···O intramolecular interactions, and the intermolecular N—H···N, O—H···O, C—H···O and C—H···N hydrogen bonds (Table 1). Molecule (b) is influenced by O—H···N and O—H···O intramolecular hydrogen bonds and N—H···N, O—H···O and two C—H···O intermolecular hydrogen bonds (Table 1).
The N1—N2 (molecule a) and N4—N5 (molecule b) bond distances of 1.3726 (15) Å and 1.3679 (16) Å, respectively, are appreciably shorter than a typical N—N single bond, such as that found in free 2,4-dinitrophenylhydrazone, i.e. 1.405 (6) Å; this suggests the existence of a delocalized double bond system (Zülfikaroğlu et al., 2009). The N1═C7 (molecule a) and N4═ C20 (molecule b) bond distances of 1.2782 (18) Å and 1.276 (2) Å, respectively, are typical for a double bond. For both molecules, the central torsion angles are C7—N1—N2—C8 at 177.63 (14)° (molecule a) and C21—N5—N4—C20 at 174.77 (14)° (molecule b). Also, the torsion angles N4—C20—C14—C15 and C23—C22—C21—N5 in the molecule (b) are 2.16 (22)° and 22.12 (20)°, respectively.
Interestingly, in the crystal the hydrogen bonding (O2—H2O···O4 and O5—H5O···O1) leads to the dimerization of the molecules (Avasthi et al., 2002) (Table 1), as shown in Fig. 2, and finally to the formation of a layer-like structure (Fig. 3).
