Abstract
In this study, the molecular structure of (E)-2-bromo-6-[(4-bromo-2-methylphenylimino)methyl]-4-chlorophenol has been investigated using crystallographic (XRD), spectroscopic (UV-vis, NMR), and computational (DFT, HOMA) methods. The refinement parameters in XRD study supports the preference of phenol-imine form by the compound in solid state. The analysis of HOMA indices indicates that C1/C6 ring (tautomeric ring) deviates slightly from the aromaticity while the C8/C13 ring preserves its aromaticity in solid state. For the solvent-media dependence of the tautomerism, UV-vis and NMR spectra of the compound were investigated. It is found that the compound prefers only phenol-imine form in solvent media as in the case of solid state.
