In this study, we report synthesis, single crystal X-ray diffraction, FT-IR and Uv-Vis. characterizations and computational investigations of the (E)-4,6-dichloro-2-[(2-chlorophenylimino)methyl]-3methoxyphenol. The tautomeric equilibrium between enol, keto and transition state (TS) forms of (E)-4,6-dichloro-2-[(2-chlorophenylimino)methyl]-3-methoxyphenol have been investigated by considering the presence of the compound in vacuum and various solvents. Experimental studies clearly reveal that the title compound has enol form in solid state and ethanol solution. In addition, the enol, keto and TS structures of the compound have been investigated computationally. Intramolecular proton transfer process on the O-H center dot center dot center dot N hydrogen bond and transition state structure during the transfer process have been studied by scan calculations for vacuum and solvent media. Moreover, the stabilization energies of the title compound were computed by using second-order perturbation theory to have insight on the intra- and intermolecular interactions, interaction among bonds, conjugative interactions. To find out most reactive sites of the title molecule, condensed Fukui functions have been calculated by means of natural population analysis. Nonlinear optical property calculations of the compound indicate that the compound can be used as a NLO material. (C) 2016 Elsevier B.V. All rights reserved.
