Decametallic Co~(II)-cluster-based microporous magnetic framework with a semirigid multicoordinating ligand

摘要

We have synthesized a microporous magnetic framework that contained supertetrahedral decametallic cobalt clusters as nodes and 4- (tris(hydroxymethyl)methyl)pyridine ligands as linkers in a NaCl-like network. This complex shows canted antiferromagnetism with spin-glass behavior. After the removal of the guest molecules, the spin-canting and spinglass behaviors are maintained. The permanent porosity was evaluated by N2-adsorption measurements. This complex mainly shows a hydrophobic nature, as validated by MeOH- and water-adsorption measurements, which is consistent with the grand canonical Monte Carlo (GCMC) theoretical simulation.
