The title compound, C34H40N2O2, exists in an extended conformation and has crystallographically imposed centrosymmetry. The crystal packing can be described as being composed of parallel layers stacked along [010]. The zwitterionic structure is stabilized by an intramolecular N—H⋯O hydrogen-bond interaction.

Ultrasonication method
A reaction flask containing 0.344g (2mmol) of 2-hydroxy-1-naphthaldehyde and 0.508g (1mmol) of 1,12-diaminododecane, mixed and ground to a fine powder in a mortar, was immersed in an ultrasonic bath containing water at a temperature of 50 °C. The reaction mixture was exposed to ultrasound irradiation for 40 min. Upon completion, based on TLC analysis (silica gel, CH2Cl2/MeOH, 9.5/0.5, V/V) the product was washed with methanol (3 x 3 mL) and diethyl ether (3 x 3 mL) and filtered. Single crystals, suitable for X-ray diffraction, were obtained after 2 days of crystallization from DMSO/MeOH.
Color: Yellow, Yield: 88 %, mp: 148°C. Analysis calculated for C34H40N2O2: C, 80.27; H, 7.92; N, 5.50%; found: C, 80.06; H, 7.80; N, 5.78%.
Conventional method
To a solution of 0.172 g (1mmol) of 2-hydroxy-1-naphthaldehyde in 5 mL of methanol was added 0.254 g (0.5 mmol) of 1,2-diaminododecane dissolved in 5 mL of the same solvent.The mixture was stirred and refluxed for 3 hours under a nitrogen atmosphere. At completion, based on TLC analysis, the resulting compound was filtered and washed with methanol and diethyl ether to afford pure product in 62% yield.
The iminium H atom was located from a difference Fourier map and refined isotropically. C-bound H atoms were included in calculated positions and treated as riding atoms: C—H = 0.95 Å (CH) or 0.99 Å (CH2) with Uiso(H) = 1.2Ueq (C—Har.).
Schiff base ligands can be easily synthesized using conventional or ultrasonic irradiation methods by reacting primary
and in which the azomethine bond is formed and they can used to form complexes (Ouari et al., 2015a., Mohammadi et al., 2012; Bhowmik et al., 2011., Grivani et al., 2013; Nejo et al., 2009., Rayati et al., 2013., Khan et al., 2014., Kanagarajan et al., 2011).The synthesis via ultrasound irradiation is an efficient, fast, high yielding method and is a more economical synthetic process for the preparation of the Schiff base compound than the conventional method.
The azomethine group >C=N of the Schiff base can form stable metal complexes by coordinating through the nitrogen atom (Ouari et al., 2015b., Ouari et al., 2010 ). Schiff base ligands have many applications including anti-microbial agents (Köse et al., 2015., Taha et al.;2012., Panneerselvam et al., 2009), anti-tumor agents, (Nasr et al., 2009) and as xanthine oxidase inhibitors (Amin et al., 2010).
This compound crystallized in the monoclinic π ring interactions. These interactions link the molecules within the layers and also link the layers together thereby reinforcing the cohesion of the ionic structure.

Similar results have been reported (Temel et al., 2010]. The crystal packing can be described as parallel chains along the c axis (Fig. 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. |
