Isolation of a stable lacunary Dawson-type polyoxomolybdate cluster

摘要

A polyoxotetradecamolybdate cluster [Mo_14O_38(OAc)_6]~2-, which has a lacunary core of the Wells-Dawson structure, is isolated by the reduction of [Mo_6O_19]~2-. The Mo_14 core is comprised of a mixed valence of [Mo~Ⅴ_4Mo~Ⅵ_10], exhibiting multi-step reversible redox processes that experience both oxidation and reduction.
