Synthesis, Structure and Properties of a New Iron(Ⅱ) Diphosphonate:[NH3(CH2)5NH3][Fe2{O3PC(CH3)(OH)(PO3H)}2]·2H2O
【摘要】 通过水热合成得到一个新的有机二膦酸亚铁化合物犤NH3(CH2)5NH3犦犤Fe2Ⅱ狖O3PC(CH3)(OH)(PO3H)狚2犦·2H2O,该化合物包含阴离子型共价双链犤Fe2Ⅱ狖O3PC(CH3)(OH)PO3H狚2犦n2n-,质子化的戊二胺和结晶水,双链之间通过强氢键构成一个开放型的骨架结构。另外,观察到亚铁离子之间存在弱铁磁性相互作用。
【Abstract】 Under hydrothermal conditions, a new iron? diphosphonate namely [NH3(CH2)5NH3][Fe2Ⅱ{O3PC(CH3)(OH)(PO3H)}2]·2H2O was synthesized and structurally characterized. The compound contains covalent double chains of [Fe2Ⅱ{O3PC(CH3)(OH)PO3H}2]n2n-, charge balanced by the protonated pentamethylenediamine. The double chains are held together by very strong hydrogen bonds, forming a three dimensional open network. Weak ferromagnetic coupling is observed for the compound.
