Source of materials

The title compound was prepared by refluxing a mixture of a solution containing 3-ethoxy-2-hydroxybenzaldehyde (0.5 g; 3.01 mmol) in 20 mL ethanol and a solution containing 4-aminobenzoic acid (0.41 g; 3.01 mmol) in 20 mL ethanol. The reaction mixture was stirred for 1 h under reflux. The crystals for the crystal structure determination were obtained from acetone by slow evaporation (yield 72%, m.p. 488–490 K).

Experimental details

All H atoms except for H1A and H4A were refined using riding models, with C—H distances of 0.96 Å for CH3 group, 0.97 Å for CH2 group and 0.93 Å for aromatic groups. The displacement parameters of these H atoms were fixed at 1.2Ueq of their parent carbon atom for aromatic groups and methylene, 1.5Ueq of their parent atoms for methyl group.

Comment

The reaction of an aldehyde and a primary amine forms the Schiff base compounds having a −C=N− double bond. These compounds have a wide range of application in the fields of coordination chemistry, biochemistry, pharmacy, nanotechnology, optical devices and textile industries [5], [6], [7]. Particularly the o-hydroxy Schiff base class is more attractive for physicists and chemists because of its interesting photo-, solvato- and thermochromic features which are caused by an intramolecular proton transfer from the hydroxyl O atom to the imine N atom with a change in the π-electronic system in the solid state. o-Hydroxy Schiff base compounds adopt OH (enol-imine/benzenoid) [8] or NH (keto-amine/quinoid) [9] tautomeric forms with reference to the location of the transferred proton.

The title compound adopts enol-imine tautomeric form and has E configuration around the C=N double bond. The bond lengths and angles are in the expected ranges and comparable with those of similar compounds in literature [10, 11] . The compound displays a strong intramolecular hydrogen bond including the atoms O1 and N1 (O⋯N = 2.588(2) Å) as a common feature of o-hydroxysalicylidene systems. As can be seen from the figure, this strong hydrogen bond constitutes a S(6) ring. In three dimensional network, the crystal structure is stabilized by an intermolecular O—H⋯O hydrogen bond and weak van der Waals interactions. The donor-acceptor distance of this intermolecular O4—H4A⋯O3′ hydrogen bond is 2.621(2) Å [symmetry code (’) = 3−x, −y, −z].
