摘要
A 2-D framework composed of a chair-like {Fe-6} cluster and BTC linkers, [Fe-6(BTC)(2)(HCOO)(6)(DMF)(6)] (1, BTC = 1,3,5-benzenetricarboxylate), has been synthesized under solvothermal conditions and characterized by elemental analysis, infrared spectroscopy, thermal gravimetric analysis, and single-crystal X-ray diffraction analysis. The {Fe-6} cluster contains six iron ions and six formate ligands, with each formate coordinating with three iron ions to construct the hexa-nuclear iron wheel. The {Fe-6} wheels are further connected via BTC ligands resulting in the first example of a 2-D framework based on {Fe-6} clusters and BTC linkers. A magnetic study indicates that intramolecular antiferromagnetic interactions exist in the hexa-nuclear iron cluster.
