Abstract

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/vl₇₂Fe^lll ₃₀} species illustrates how Raman-monitored synthesis can result in such clusters comprising a welldefined assembly of spin centers.
