Abstract
The synthesis processes of 5-methoxy-2-[( E)-( 6-methylpyridin-2-ylimino) methyl]phenol was studied on the reaction of2-hydroxy-4-methoxybenzaldehyde and 2-amino-6-methylpyridine. The maximum yield was obtained between 2-hydroxy-4-methoxybenzaldehyde and 2-amino-6-methylpyridine with a molar ratio of 1∶ 1. 6 under the temperature of 75℃ for 6 h. The structure of the product was characterized by elemental analysis,UV-Vis,IR,1H NMR and X-ray single crystal diffraction. The compound crystallizes in the monoclinic system space group P21/ c with a = 1. 1886( 3) nm,b = 0. 65948( 16) nm,c = 1. 6897( 4) nm,β = 108. 505( 3) °,V = 1. 2560( 5) nm3,Dc= 1. 281 g·cm- 3,Z = 4,F( 000) = 512,μ = 0. 087 mm- 1,R1= 0. 0477,wR2= 0. 1342. The structure of the object compound features a stable crystal structure constructed by π…π packing and intramolecular hydrogen bond O2-H2…N1,C8-H8A…N2,with blue fluorescence.
