Synthesis method and crystal structure of novel mixed valence Mo^Ⅴ-Mo^Ⅵ polymetallate cluster Na₃H₃[H₈Mo₅₇Fe₆^ⅡO₁₈₅（NO）₆（H₂O）₁₆（MoO）₂]·81H₂O

【摘要】 <正> Understanding the driving force for the formation of high-nuclearity clusters is still aformidable challenge. Recently, we have reported two crystal structures with the largestpolymetallate clusters involving mixed-valence molybdenum and vanadium （Ⅳ） or Fe （Ⅲ）, ofwhich the Mo; V and Mo; Fe ratios are 57:6. Here we report the crystal structure ofnew heteropolyanion involving mixed-valence molybdenum and Fe（Ⅱ）. [H₈Mo₅₇Fe₆^ⅡO₁₈₅（NO）₆·（H₂O）₁₆（MoO）₂]^6-,of which the Mo:Fe ratio is as high as 59:6.更多还原
