Abstract

Vapor-induced crystal to crystal transformation between non-polar [Fe(sap)(acac)(sol)] (H₂sap = 2-salicylideneaminophenol, acac = acethylacetate, sol = MeOH, pyridine) and polar [Fe(sap)(acac)(DMSO)] was demonstrated. It provides an example of switchable ferroelectric behaviour attributted to the structural phase transition triggered by solvent vapour.
