The direct synthesis of Fe-3-MIL-88B and Fe2Ni-MIL-88B was analyzed using different characterization techniques including UV-vis, IR, and Raman spectroscopies and XRD. It was found that single metal Fe-3-MOF-235 seeds which were formed from the first stage of synthesis are precursors for the formation of MIL-88B. Fe-3-MOF-235 seeds formed in the first stage of synthesis were then transformed to Fe3-MIL-88B in the case of single metal, and to mixed Fe2Ni-MIL88B in the case of mixed metal synthesis. In the both cases of Fe-3-MIL-88B and Fe2Ni-MIL-88B, the FeCl4- anion is a key feature for the formation of MOF-235. An anion-mediated mechanism for the formation of the MOF-235 structure is also suggested.
