1 Source of materials
2-Hydroxy-1-naphthaldehyde (0.02 mol 3.4436 g), sodium bisulfite (0.03 mol 3.1215 g) and 4,5-dimethylbenzene-1,2-diamine (0.06 mol 8.172 g) were suspended in methanol (70 g). Under nitrogen atmosphere, the suspension was stirred at 60 °C for 24 h. The mixture was cooled to room temperature, filtered, concentrated under pressure and purified by silica gel column chromatography (hexane : ethyl acetate = 2:1, v/v, R f = 0.83). Crystals of the title compound were obtained by slow evaporation of the elution of the target at room temperature.
2 Experimental details
Absorption corrections were used by using multi-scan program [1]. The structure was solved with Olex2 and Shelx [2], [3], [4]. Hydrogen atoms were placed in their geometrically idealized positions. Hydrogen atoms were constrained to ride on their parent atoms.
3 Comment
Schiff bases are a class of compounds formed by double bonding between carbon atoms and nitrogen atoms, their excellent coordination structure main due to the presence of C=N in the structure [5]. Schiff bases are widely used in the construction of coordination compounds [6]. Schiff bases and their metal complexes have different application prospects in magnetic material, catalysis, analytical chemistry, medicine, new energy materials, luminescence, or other fields [7, 8].
The title molecule in the crystal structure is a flexible molecule and each title molecule contains one phenyl ring, one naphthyl ring and one C=N double bond. From the data of bond length and bond angle of the title Schiff base compound, it can be seen that the C=N double bond length N2⋯C9 in Schiff base is 1.299(7) Å, which is similar to the average bond length of the usual C=N double bond [9]. In the title molecule, the C–C distances are in the range of 1.346(9) to 1.508(9) Å, the C–N distances are in the range of 1.375(8) to 1.405(7) Å, the C=O distance is 1.293(7) Å.
In addition, there are one intermolecular C–H⋯π interaction among the aromatic rings from neighboring molecules. The C–H⋯π interaction is C1–H1C⋯Cg i (C3–C8; symmetry code i: x, y, 1 + z), the shortest distance between H1C and center of Cg1 i is 2.93 Å [10]. Also the crystal packing is consolidated by hydrogen bond interactions. The first hydrogen bond is N1–H1A⋯N1, the distance of H1A⋯N1 bond is 2.53(8) Å, the angle of N1–H1A⋯N1 is 136(6)°. The second hydrogen bond is N1–H1B⋯O1, the distance of H1B⋯O1 bond is 1.96(7) Å, the angle of N1–H1B⋯O1 is 161(5)° [11]. The third hydrogen bond is N2–H2⋯O1, the distance of H1B⋯O1 bond is 1.87 Å, the angle of N2–H2⋯O1 is 135°, its intramolecular hydrogen bond. The fourth hydrogen bond is N2–H2⋯N1, the distance of H1B⋯O1 bond is 2.45 Å, the angle of N2–H2⋯N1 is 103°, its intramolecular hydrogen bond [12]. In general all geometric parameters are in the expected ranges [13].
