2-Hydroxy-1-naphthaldehyde (1 mmol, 172.2 mg) were added with stirring to anhydrous ethanol (30 ml) to make a solution. It was slowly dropped into the anhydrous ethanol solution (15 ml) containing (1 mmol, 108.1 mg) 5-methylpyridin-2-amine at 339 K and mixture was stirred at 339 K for 4 h, a mass of deep yellow grain was separated out. The product was collected by filtration and washed several times with anhydrous ethanol and dried under vacuum. Yellow needles of (I) were obtained by slow evaporation at room temperature from anhydrous ethanol solution after 4 days.
Anomalous dispersion was negligible and Friedel pairs were merged before
All H-atoms were positioned geometrically (C—H = 0.93–0.96Å, N—H = 0.86Å) and refined as riding with Uiso(H) =1.2Ueq(carrier).One similar compound as 1-{2-[(2-hydroxy-1-naphthyl)methyleneamino] phenyliminiomethyl}-2-naphtholate methanol hemisolvate has been synthesized and characterized by X-ray diffraction (Eltayeb et al., 2007). We now report on the title compound, (I), whose structure was determined by X-ray diffraction (Fig. 1).
This compound, which has a non-planar molecular structure, contains two aromatic rings linked through a imine group. The dihedral angle between the two aromatic rings C2—C3—C4—C5—N1—C6 and C8—C9—C14—C15—C16—C17 is 3.46(0.16)°. Intramolecular N—H···O hydrogen bonds are observed in the molecular structure, similar to those reported structure (Eltayeb et al., 2007). The molecules is formed a one-dimensional zigzag chain through intermolecular C—H···O hydrogen bonds, which make the molecule more stabile.
As seen in Fig. 2, the molecules are linked into a one-dimensional chain by intermolecular C—H···O hydrogen bonds (Table 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. |

One similar compound as 1-{2-[(2-hydroxy-1-naphthyl)methyleneamino] phenyliminiomethyl}-2-naphtholate methanol hemisolvate has been synthesized and characterized by X-ray diffraction (Eltayeb et al., 2007). We now report on the title compound, (I), whose structure was determined by X-ray diffraction (Fig. 1).
This compound, which has a non-planar molecular structure, contains two aromatic rings linked through a imine group. The dihedral angle between the two aromatic rings C2—C3—C4—C5—N1—C6 and C8—C9—C14—C15—C16—C17 is 3.46(0.16)°. Intramolecular N—H···O hydrogen bonds are observed in the molecular structure, similar to those reported structure (Eltayeb et al., 2007). The molecules is formed a one-dimensional zigzag chain through intermolecular C—H···O hydrogen bonds, which make the molecule more stabile.
As seen in Fig. 2, the molecules are linked into a one-dimensional chain by intermolecular C—H···O hydrogen bonds (Table 2).
