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.eninfo:eu-repo/semantics/closedAccessSolid-StatePhotochromismTautomerismCrystalProtonArticle65346346710.1134/S10637745200301532-s2.0-85085490202Q4WOS:000536643700028Q4
