Abstract
Two novel cluster-organic frameworks based on the 12-nuclearity manganese-cluster secondary building unit (SBU), [MnIII4MnII8(L)4(Ac)8(MeO)2(μ5-O)2(H2O)4](Ac)2·16H2O (1) and [MnIII4MnII8(L)4(Ac)8(MeO)2(μ5-O)2(H2O)4](Ac)2·12H2O (2), where Ac = CH3COO- and MeO = CH3O, have been constructed from solvothermal reactions of the 3-nuclearity manganese cluster [Mn3(μ3-O)(Ac)6(py)3](ClO4) (Mn3, 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.
