  Abstract

HCrO4-에 의한 [Mo3O4(C2O4)3(H2O)3]2-의 산화는 몰리브덴(Ⅳ)화합물, [Mo2O5(C2O4)2(H2O)2]2-를 생성한다. HCrO4-와 [Mo3O4(C2O4)3(H2O)3]2-의 반응에 대한 화학양론은 2Mo3Ⅳ + 4CrⅥ → 3Mo2Ⅵ + 4CrⅢ와 같다. 관찰된 속도상수는 수소이온농도에 의존한다. CrⅥ는 CrⅤ와 CrⅣ를 거쳐서 CrⅢ로 일전자씩 연속적으로 변화한다. 상세한 메카니즘이 논의된다. Oxidation of [Mo3O4(C2O4)3(H2O)3]2- with HCrO4- yields the molybdenum(Ⅳ) complex, [Mo2O5(C2O4)2(H2O)2]2-. Stoichiometry for the reaction of [Mo3O4(C2O4)3(H2O)3]2- with HCrO4- are expressed as 2Mo3Ⅳ + 4CrⅥ → 3Mo2Ⅵ + 4CrⅢ. Observed rate constants are dependent on hydrogen ion concentration. The kinetic data are consistent with a mechanism in which three successive single-electron steps convert CrⅥ to CrⅢ by way of intermediate CrⅤ and CrⅣ. Detailed mechanisms are presented and discussed.
