The aim of this research is to establish how metal-organic frameworks (MOPS) composed of More than one metal in equivalent crystallographic sites (solid solution MOFs) exhibit catalytic activity, which is tunable by virtue of the metal ions ratio. New MOFs with general formula [InxGa1-x(O2C2H4)(0.5)(hfipbb)] Were prepared by the combination of Ga and In. They are isostructural with their monometal counterparts, synthesized with Al, Ga., and In. Differences in their behavior as heterogeneous catalysts in the three-component, one pot Strecker reaction illustrate the potential of solid solution MOFs to provide the ability to address the various stages involved in the reaction mechanism.
