Ion exchange has been a well-studied area specifically when it comes to the family of Dion-Jacobson (DJ) perovskites general formula A[A'(n-1)B(n)X(3n+1)]. The method allows for the replacement of interlayer cations for other cations like protons, alkali metals, polyatomic ions; aliovalent exchange with alkaline earths and transition metal cations; and co-exchange of metal-halides. Our group has shown the ability to insert metal-chloride layers within layered perovskites resulting in compounds like (MCl)LaNb2O7 (where M = Cr, Mn, Fe, Co, Cu)  The research herein focuses on further study of metal-chloride conversions starting with DJ host compounds from the niobate, and tantalate oxide perovskites where n = 1,2. Details on the synthesis and characterization of new layered compounds prepared will be presented and discussed.
