Cross-Linking CdSO-Type Nets with Hexafluorosilicate Anions to Form an Ultramicroporous Material for Efficient CH/CO and CH/CH Separation.

A 4.6.8 topology hybrid ultramicroporous material (HUM), {[CuF(SiF)(L)]·G}, (L = 4,4'-bisimidazolylbiphenyl, G = guest molecules), 1, formed by cross-linking interpenetrated 3D four-connected CdSO-type nets with hexafluorosilicate anions is synthesized and evaluated in the context of gas sorption and separation herein.

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.
