The title Schiff base compound, C33H30N4O4·H2O, adopts an E configuration with respect to each C=N double bond. In the molecule, there are naphthoxide anions and the protonated imino N atoms. Intramolecular N—H⋯O hydrogen bonds lead to the formation of approximately planar (maximum deviation 0.029 Å for H atom) six-membered rings.. In the crystal, molecules are linked by O—H⋯O and N—H⋯O hydrogen bonds as well as C—H⋯O contacts, leading to the formation of a three-dimensional network.

A solution of NaOH (3 mmol) in methanol (10 cm3) was added to a suspension of N1-(2-nitrobenzyl)-N1-(2-aminoethyl)ethane-1,2- diamine trihydrochloride (0.357 g, 1 mmol) in methanol (10 cm3). The mixture was stirred at room temperature for a few minutes then filtered, and the precipitate was washed well with methanol (10 cm3). The washings and the filtrate were combined and to this solution was added 2-hydroxy-1-naphthaldehyde (0.344 g, 2 mmol). After refluxing the solution for 8 h on cooling the product was recovered as a yellow powder, which was recrystallized from methanol.
Several H atoms were located on final difference map. However, the H atoms were included in the

A number of the π-π interactions between the naphthalene moiety and the nitrobenzene moiety with the distance of 3.516 (3) Å. The structural features of I (The bond lengths) provides evidence for the existence of a naphthoxide anions and the protonated imino N atoms in the of I that stabilize by intramolecular hydrogen bond between the naphtholate oxygen and the iminium nitrogen (O-···H—N+). This is determined by the formation of pairs of intramolecular N±–H···O– (1.888 (3) Å) hydrogen bonds. These interactions lead to the formation of six- membered rings (see scheme). Details of the hydrogen-bonding geometry are given in Table 1. Each of these hydrogen-bonded rings adopts a nearly planar conformation. In the six-membered rings, the maximum deviation from the mean planes is 0.029 Å for H (N±–H). The crystal packing in compound (1) is stabilized by O—H···O– interactions (Fig. 2 and Table 1).

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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 (imines) are known to be good ligands for metal ions. A number of the Schiff bases have antitumor properties, antioxidative activities, attractive electronic and photophysical properties. In addition, Schiff base derivatives incorporating a fluorescent moiety are appealing tools for optical sensing of metal ions (Azadbakht et al. 2011). The title compound, (I), crystallizes in the Monoclinic space group P2(1)/c. Figure 1 shows the ORTEP representation of the molecule with thermal ellipsoids at the 30% probability level. In the compound, there are π-π interactions between the naphthalene moiety and the nitrobenzene moiety with the distance of 3.516 (3) Å. The structural features of I (The bond lengths) provides evidence for the existence of a naphthoxide anions and the protonated imino N atoms in the crystal structure of I that stabilize by intramolecular hydrogen bond between the naphtholate oxygen and the iminium nitrogen (O-···H—N+). This molecular conformation is determined by the formation of pairs of intramolecular N±–H···O– (1.888 (3) Å) hydrogen bonds. These interactions lead to the formation of six- membered rings (see scheme). Details of the hydrogen-bonding geometry are given in Table 1. Each of these hydrogen-bonded rings adopts a nearly planar conformation. In the six-membered rings, the maximum deviation from the mean planes is 0.029 Å for H (N±–H). The crystal packing in compound (1) is stabilized by O—H···O– interactions (Fig. 2 and Table 1).
