Synthesis and X-ray diffraction data of N1,N2-di(2-hydroxy)benzylidenbenzene-1,2-di-imine, C20H16N2O2

Abstract

The Schiff base N1,N2-di(2-hydroxy)benzylidenebenzene-1,2-di-imine was prepared from salicylaldehyde and 1,2-diaminobenzene by reflux in ethanol for 6 h obtaining an orange crystalline solid. The Schiff base solid was separated by filtration and washed with ethanol and ethylic ether, and finally, it was dried in a vacuum system for 2 h. The X-ray powder diffraction pattern for this new compound showed that the crystalline compound belongs to the monoclinic system and space group P21/c (No. 14) with refined unit-cell parameters a = 5.9672 (7) Å, b = 16.561 (1) Å, c = 16.337 (2) Å, β = 91.41° (1). The volume of the unit cell is V = 1614.1 (2) Å3.
