Sc(iii)-Based metal–organic frameworks

Abstract

Scandium(III) ions can form robust metal-organic frameworks (MOFs) with relative ease of synthesis. However, their use in MOF construction remains scarce compared to the vast collection of MOFs using other...

A Multi-metal Approach for the Reticulation of Iridium into Metal-Organic Framework Building Units

“…Similarly to indium, it usually affords highly robust and stable frameworks, (48) and moreover, there are examples of isostructural MOFs reported with indium or scandium, (40,49) as well as MOFs with SBUs comprised of scandium trimers and chains. (50,51) Bearing this in mind, the strategy of using scandium as a substitute for the indium atoms was successful, as the combination of iridium chloride, scandium nitrate and 2,5-H2PDC in water resulted in the formation of a compound isostructural to InIrPF-13.…”

Sacrificial-Hydroxamate-Enabled Sizable Crystallization of Scandium Carboxylate Metal–Organic Frameworks

“…We expect that this sacrificial modulation strategy would benefit the formation of sizable single crystals of desirable MOFs. Considering that scandium carboxylate MOFs (Sc-MOFs) have shown promising and unique properties in catalysis and gas-related applications, − many Sc-MOFs have been developed over the years. Yet, as a typical trivalent metal should behave, several notable Sc-MOFs (e.g., MIL-88, MIL-100, MIL-101, and PCN-333) − from conventional (modulated) synthesis crystallized only in small sizes and were found to be unfit for SC-XRD studies.…”
