Construction of High-Nuclearity Manganese-Cluster-Organic Frameworks by Using a Tripodal Alcohol Ligand.

Two novel cluster-organic frameworks based on the 12-nuclearity manganese-cluster secondary building unit (SBU), [MnMn(L)(Ac)(MeO)(μ-O)(HO)](Ac)·16HO (1) and [MnMn(L)(Ac)(MeO)(μ-O)(HO)](Ac)·12HO (2), where Ac = CHCOO and MeO = CHO, have been constructed from solvothermal reactions of the 3-nuclearity manganese cluster [Mn(μ-O)(Ac)(py)](ClO) (Mn, where py = pyridine) with a tripodal alcohol ligand containing a 4-pyridyl group. 1 and 2 represent the first examples of metal-organic frameworks containing 12-nuclearity manganese-cluster SBUs. In addition, 1 exhibits an integration of the porosity and magnetic properties from both the framework and cluster in a porous material.
