Abstract: The oxidation of dimethylhydrazine hydrazine and hydroxylamine by 12-tungsto-balt (Ⅲ) ate in acetate buffer solution were investigaied.In the pH range of the experiment,all the systems have a similar empirical rate equation: r=d[K5Co(Ⅲ)W12O40]/dt=[K5Co(Ⅲ)W12O40][R]T/[H+] The values of the activation parameters of the reactions were given.A mechanism of electron transfer through hydrogen bonding was suggested.

Key words: cage complex, oxidation reaction, electron transfer
