Metal-organic frameworks (MOFs) are a new class of new generation nanoreactors that are composed of various metals and organic compounds as ligands. Recently, various metals such as Zr, Co, Fe, Ti have been used in bimetallic MOFs architectures. These nanostructures have shown unique properties and the limitations of monometallic MOFs can be compensated with such hybrid systems[1].Click chemistry is one of the most effective methods of producing organic compounds and various catalysts, which has attracted the attention of many scientists and industries in the last decade. By using click chemistry, it is possible to modify the structure of many MOFs and turn them into targeted and effective catalysts for catalytic and photocatalytic purposes [2-3]. Our aim is to design a MOF based on two metals Co and Fe to create a bimetal-organic frameworks. The catalytic application of this structure has been evaluated in the reaction of preparing spiro compounds under green and mild conditions, and the results prove the suitability of such a catalytic system (Scheme 1).
