摘要： 用XPS测定了5种含FeⅢ杂多阴离子中Fe2p和O1s的结合能及Fe2p3/2的伴峰强度。结合磁化率和差减红外光谱,研究了杂多阴离子中铁的自旋态。证实二聚体(SiFeW11)2O中含有Fe—O—Fed-pπ键,相邻铁原子上的d电子发生了反磁性交换。讨论了骨架原子及中心原子对杂多阴离子中铁的电子云密度的影响。

Abstract: The intensity of Fe2p3/2 satellite peaks and the binding energies of Fe2p3/2 and O1s. for five het-eropolyanions were determined. The IR spectra and the magnetic susceptibility in these anions were obtained. The spin state of FeⅢ in the anions was deduced. The d-pπ bond of Fe-O-Fe bridge in (SiFeW11)2O was identified. The effects of the frame- and center hetero-atoms on the electron cloud density of iron in the anions are discussed.
