Three-dimensional metal-organic framework based on pentanuclear manganese clusters as building blocks

摘要

A rare 3-D Mn-organic framework, [(CH3)(2)NH2](3)[Mn-5(btc)(4)(Ac)(H2O)(4)]5H(2)O (1), based on pentanuclear manganese clusters as building blocks has been prepared and structurally characterized by EA, IR, TGA, PXRD, and single-crystal X-ray diffraction. Structural analysis indicates the pentanuclear manganese cluster in 1 has a bow-like configuration, which is the first found to act as secondary building unit in the field of metal-organic framework. Gas adsorption measurements reveal that 1 can absorb a considerable amount of N-2 and CO2.
