A high-nuclearity isopolyoxotungstate based manganese cluster: one-pot synthesis and step-by-step assembly†
Abstract
A manganese(III,IV)–tungsten(VI) supercluster based on 72 manganese ions (48 MnIV and 24 MnIII) and 48 tungsten(VI) centers [{MnIV24MnIII12O28(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.
