Solvothermal Synthesis,Crystal Structure and Property of a Three-dimensional Fe(Ⅱ)Complex:[Fe(INAIP)(DMF)]n·0.5nDMF

A Fe-based metal-organic framework, [Fe（INAIP）（DMF）] n ·0.5nDMF（1）, has been synthesized by the reaction of 5-（isonicotinamido）isophthalic acid（H 2 INAIP） with FeSO 4 ·7H 2 O under DMF reaction solvent. Single-crystal X-ray diffraction analysis indicates that complex 1 displays a two-fold interpenetrated three-dimensional（3D） framework with sra topology. The TG, magnetic and adsorption properties of the complex were also studied.
