The new Schiff base of compound was synthesized and characterized by XRD, FTIR, UV-Vis and NMR techniques. The structure with two molecules in its asymmetric unit showed the enol-imine form in one and the keto-amine form in the other. Both tautomeric forms are stabilized by strong O-H horizontal ellipsis N and N-H horizontal ellipsis O intramolecular hydrogen bonds. Optimized geometrical parameters and calculated spectroscopic features obtained by DFT/B3LYP/6-31G(d,p) calculations show a good agreement with the experimental data. Accordingly local and global chemical activity descriptors were investigated.
