In the search of Ni based metal–organic frameworks (MOFs) containing paddle-wheel type building units, three chemical systems Ni2+/HnL/base/solvent with HnL = H3BTC (1,3,5-benzenetricarboxylic acid), H3BTB (4,4′,4′′,-benzene-1,3,5-triyl-tris(benzoic acid)), and H2BDC (terephthalic acid) were investigated using high-throughput (HT) methods. In addition to the conventional heating, for the first time HT microwave assisted synthesis of MOFs was carried out. Six new compounds were discovered, and their fields of formation were established. In the first system, H3BTC was employed and a comprehensive HT-screening of compositional and process parameters was conducted. The synthesis condition for the Ni paddle-wheel unit was determined and two compounds [Ni3(BTC)2(Me2NH)3]·(DMF)4(H2O)4 (1a) and [Ni6(BTC)2(DMF)6(HCOO)6] (1b) were discovered (Me2NH = dimethylamine, DMF = dimethylformamide). In the second system, the use of the extended tritopic linker H3BTB and the synthesis conditions for the paddle-wheel units le...

The direct synthesis of Fe3-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 Fe3-MOF-235 seeds which were formed from the first stage of synthesis are precursors for the formation of MIL-88B Fe3-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 Fe3-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
