摘要
二茂铁衍生物l-二茂铁基3-苯基丙-2-烯-1-酮(FcBAK)与钼磷酸盐Na2HPMo12O40·xH2O经室温固相合成得到有机-无机杂化分子,通过元素分析、IR、ICP、AAS和TG等表征手段确证产物的分子组成和结构为(FcBAK)3HPMo12O40·2H2O.固体电子光谱及ESR谱表明,FcBAK与钼磷酸之间发生了电荷转移作用,生成电荷转移型有机-无机分子复合物,该复合物的磁学行为表现出较强的铁磁性质,粉末样品的室温饱和磁化强度为0.41A·m2/kg,矫顽力为0.0105T,属于软磁性有机-无机分子复合材料.
A novel organic-inorganic molecule with a composition of [Fe（C5H5）2COC2H2C6H5]3HPMo12O40·2H2O was synthesized by solid-state reaction at room temperature. The compound was characterized via elemental analysis, IR, ICP, AAS, TG. The results of solid electronic absorption spectra and ESR spectra show that charge transfer between Fe （C5H5 ）2COC2H2C6H5 （1-ferrocenyl-3-benzoyl-2-alkene-1-ketone, short of FcBAK） and polyoxometalate anion（molybdophosphoric） took place and the polyoxometalate anion formed a mixed valence compound. Magnetic measurement result shows that the compound is a ferromagnetic materials, with its Ms =0. 41 A · m^2/kg, He = 0. 0105 T. The relationship between the structure and magnetic propety has been discussed. This work provides a way for design and synthesis of novel organic-inorganic magnetic materials
