Redox‐controlled magnetism : The partial reduction of polyoxomolybdate building blocks in Keplerate cluster structures allows the magnetic superexchange mediated by these diamagnetic blocks to be altered. The isolation of a 16‐fold reduced {Mo V/VI 72 Fe III 30 } species illustrates how Raman‐monitored synthesis can result in such clusters comprising a well‐defined assembly of spin centers.
