Abstract

A manganese(III,IV)–tungsten(VI) supercluster based on 72 manganese ions (48 Mn^IV and 24 Mn^III) and 48 tungsten(VI) centers [{Mn^IV₂₄Mn^III₁₂O₂₈(H₂O)₂₃}₂(W₂₄O₁₂₀)₂]⁴⁰⁻ has been prepared from the carboxylic Mn₁₂ cluster. Its structure comprises two unprecedented cage-like Mn₃₆W₂₄ cores linked via two Mn–O–W bonds, leading to a Mn₇₂W₄₈ assembly. The inorganic synthetic mechanism was investigated through different synthesis methods and comprehensive ESI-MS tests.
