摘要
The sodium salts of two heteropoly anions, [Co6W18O70H8](12)- and [Fe6W18O70H2](12)- have been isolated in the crystalline form. Evidence from chemical analyses, Fast Atom Bombardment mass spectroscopy (FABMS), infrared spectroscopy (IR), ultraviolet spectroscopy (UV), visible spectroscopy, and cyclic voltammetry support the above formulations. The structure of these anions is believed to be similar to the Weakley structure in which two half Keggin structures sandwich between them four metal ions of octahedral coordination.
