The synthesis of rare-earth cluster-based MOFs is often performed using metal nitrate salts as precursors. In this work, we demonstrate that six other Y(III) precursors can be used as alternatives in the synthesis of Y-CU-45 (CU = Concordia University), yielding reproducible results and high-quality materials.
