All reagents and solvents were used as obtained commercially without further purification. The title compound was prepared according to the reported procedure (Zhang et al., 1999). A solution of methyl carbazate (0.09 g, 1 mmol) in 5 ml of ethanol was added slowly to a solution of 2-hydro-1-naphthaldehyde (0.172 g, 1 mmol) in 15 ml absolute ethanol, under heating and stirring. The mixture was refluxed for 3 h, then cooled to room temperature and left to stand in air for 5 days. Yellow block-shaped crystals were formed on slow evaporation of the solvent.
H atoms bonded to C atoms were placed geometrically and treated as riding, with C—H distances 0.93–0.96 Å and Uiso(H) = 1.2Ueq(C) for the CH, while Uiso(H) = 1.5Ueq(C) for the CH3 groups. The amide H atoms were located from difference maps and refined with the N—H distances restrained to 0.86 Å and Uiso(H) = 1.2Ueq(N). The hydroxyl H atoms were located from difference maps and refined with the O—H distances restrained to 0.82 Å and Uiso(H) = 1.5Ueq(O).
The naphthalene group as a fluorophore has been studied extensively due to its characteristic photophysical properties and the competitive stability in the environment (Li et al., 2010; Iijima et al., 2010). Schiff base metal complexes have been widely studied because they have industrial, antifungal, antibacterial, anticancer and herbicidal applications (Cozzi, 2004). As part of an ongoing study of
incorporating the naphthalene group (Xu et al., 2009), we report here on the of the title compound.The molecular structure of the title compound is shown in Fig. 1 and geometrical parameters are given in the archived
The title molecule, adopts an E or trans configuration with respect to the C=N bond while the lengths and angles are within normal ranges. The C=N bond length is 1.288 (2) Å, a little longer than schiff base C=N bond length (1.280 (15) Å) (Xu et al., 2009).The of (I) is stabilized by one intramolecular O—H···N interaction with H···N distances 1.91Å and O—H···N angles is 146.1° and one intermolecular N—H···O interaction with H···O distances 2.11Å and N—H···O angles is 169.8°, Table 1. The molecules are linked in C(4) chains along [100], (Bernstein et al., 1995), Fig. 2.For the naphthalene group as a fluorophore, see: Li et al. (2010); Iijima et al. (2010).

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. |

The naphthalene group as a fluorophore has been studied extensively due to its characteristic photophysical properties and the competitive stability in the environment (Li et al., 2010; Iijima et al., 2010). Schiff base metal complexes have been widely studied because they have industrial, antifungal, antibacterial, anticancer and herbicidal applications (Cozzi, 2004). As part of an ongoing study of Schiff bases incorporating the naphthalene group (Xu et al., 2009), we report here on the crystal structure of the title compound.
The molecular structure of the title compound is shown in Fig. 1 and geometrical parameters are given in the archived CIF. The title molecule, adopts an E or trans configuration with respect to the C=N bond while the lengths and angles are within normal ranges. The C=N bond length is 1.288 (2) Å, a little longer than schiff base C=N bond length (1.280 (15) Å) (Xu et al., 2009).The crystal structure of (I) is stabilized by one intramolecular O—H···N interaction with H···N distances 1.91Å and O—H···N angles is 146.1° and one intermolecular N—H···O interaction with H···O distances 2.11Å and N—H···O angles is 169.8°, Table 1. The molecules are linked in C(4) chains along [100], (Bernstein et al., 1995), Fig. 2.
