摘　　要：在水热条件下,用Na10[α-SiW9O34]·18H2O,Fe2(SO4)3与phen反应合成了一种有机-无机杂化Keggin型硅钨酸盐[FeII(phen)3]2[α-SiW12O40]·H2O(1),并借助IR光谱、X射线光电子能谱和单晶X射线衍射等对其结构进行了表征.晶体学研究表明化合物1的分子由1个饱和的[α-SiW12O40]4-多阴离子、2个[FeII(phen)3]2+配离子和1个结晶水分子构成,其中3个1,10-菲啰啉分子中的6个氮原子与Fe2+离子配位形成了八面体构型.Under hydrothermal conditions, an organic-inorganic hybrid Keggin silicotungstate [Fe^（Ⅱ）（phen）_3]_2[α-SiW_（12）O_（40）]·H_2O （1） （phen = 1,10-phenanthroline） was made by reaction of Na10[α-SiW9O34]·18H2O,Fe2（SO4）3 and phen and it was characterized by IR spectrum, X-ray photoelectron spectroscopy （XPS） and single-crystal X-ray diffraction. X-ray crystallog- raphy reveals that the molecular structure of polyoxoanion, two dissociative coordination [Fe（phen）3]2＋ cation is defined by 1 is constituted by one saturated [α-SiW12O40]4- Fe（phen）3]2＋ cations and one lattice water mole- six nitrogen atoms from three phen ligands.
